License Info and press Deactivate. Now the license key can be used to install PTGui on the new computer. If you can no longer access the computer please go to your accountand request us to deactivate your computer (but note that this may take up to 24 hours).

PTGui 10 and earlier can be deactivated by going to the About window, press Register and then press the Deactivate button. On Windows, PTGui Pro mac Archives, 'About' can be found in the Help menu; on macOS it's in the 'PTGui [Pro]' menu.

2.7. On how many computers is my license activated?

Go to your accountand login with your license key to see the currently activated computers.

2.8. I lost my license key

No problem; you can retrieve the license key in your account. Be sure to login with the email address used for purchasing the license.

2.9. I'm planning to switch from a PC to a Mac computer, is that a problem?

No problem, the license is platform independent and you will be able to transfer the license to another computer, PTGui Pro mac Archives.

2.10. We are running PTGui on multiple computers in a network environment. How can we deploy PTGui without activating each computer manually?

Each computer running PTGui must be activated. The activation process keeps track of the number of computers on which a PTGui license is used. Normally PTGui will ask for the license key to activate the software when it is run for the first time on a computer. This step can be automated by installing a provisioning file containing the license key. If such a provisioning file is present, the user does not have to enter the license key and PTGui will be activated automatically when it is run for the first time on a computer, using a PTGui Pro mac Archives key from the provisioning file.

The provisioning file must be stored in this location on Windows computers:C:\ProgramData\PTGui\licensekey.jsonOn macOS:/Users/Shared/Application Support/PTGui/licensekey.jsonOn Linux:/etc/PTGui/licensekey.json
licensekey.json should be a JSON file with the following IDM Crack "licensekeys": [ { "regkey": "QjAfghfh444466663Ykk/RJd2vdcfSqYG9cxoP5s/+JGmAoqKWk%BacGWgCAQ==" }, { "regkey": "MzQyQ+rtret8778h1998y9erkk4889384898hjkjkjjycGWgCAQ==" } ] }
If a proxy server is required for internet access, a "proxy" section can be added as follows:
{ "licensekeys": [ { "regkey": "QjAfghfh444466663Ykk/RJd2vdcfSqYG9cxoP5s/+JGmAoqKWk%BacGWgCAQ==" } ], "proxy": { PTGui Pro mac Archives "url": "http://ip.address.of.proxy:8888", "user": "userNameForProxy", "password": "secretPassword" } }
Even if the "proxy" section is missing in the .json file, existing proxy settings (if any) in the PTGui configuration will still be used. The proxy settings can be edited in Options - Advanced. If the proxy settings are included in the .json file, the settings in the PTGui configuration will be updated whenever licensekey.json is used for activation.

The file can contain multiple license keys (2 in the first example above); PTGui will attempt to activate using the keys in this order. If a key is already activated on another computer, the next key will be used, until activation is succesful.

Note that PTGui license keys consist of two lines, but strings in JSON must be represented in a single line. PTGui ignores line endings in the license key, so the two lines of the license key can simply be concatenated into a single line. You can validate the syntax of your JSON file using (e.g.) JSONLint.

If activation fails, an error message is displayed and PTGui will show the regular activation window, PTGui Pro mac Archives. The provisioning file will only be used if PTGui is not yet activated, PTGui Pro mac Archives. If PTGui is already activated on a particular computer, licensekey.json will be ignored.

To install PTGui on multiple Windows computers in the network you can script your deployment system to run the PTGui installer in silent mode as follows (replace PTGuiSetup.exe with the actual file name of the installer):PTGuiSetup.exe /S /D=C:\Program Files\PTGuiNote that the options are case sensitive, so use a capital /S and /D. The installer can be run without uninstalling a previous version first.

On a Mac no PTGui Pro mac Archives is necessary, just copy the PTGui application bundle into the Applications folder.

A license can be deactivated on a computer as usual, through Help - License Info - Deactivate from within PTGui PTGui Pro mac Archives the licensed computer. If this is not possible, remote deactivation can be requested from your account. Be sure to remove licensekey.json after deactivation, otherwise PTGui will be reactivated automatically and silently when it is launched again.

For activation PTGui needs to be able to contact the activation server (see Q2.11). Also, PTGui needs to be able to create the file C:\ProgramData\PTGui\reg.dat and update it occasionally (reactivation is needed every 30 days) so appropriate permissions to this folder must be given to all users running PTGui.

2.11. PTGui says 'failed to activate your license'. How can I resolve this?

To activate your license on your computer PTGui needs to contact the license server. This may fail if there is no internet connection or if the computer is behind a corporate firewall.

If there is a firewall, it should be configured to permit outgoing network connections to activation1.ptgui.com on TCP port 443. If necessary PTGui can use a proxy server to access the internet (see Q2.12).

If internet access is not available or restricted, PTGui offers an offline activation option: in the activation window press the Activate Offline button and follow the instructions.

2.12. My internet connection is behind a proxy server. How can I activate PTGui?

A proxy server can be configured by pressing the Proxy button in the activation window, or in Options / Preferences - Advanced. Enter the URL of the proxy server, including the protocol and port number. For example:

http://proxy.example.com:8888 (HTTP proxy)
socks5://proxy.example.com:1080 (SOCKS proxy)

An HTTP proxy server should support the CONNECT keyword for HTTPS connections.

2.13. Can a license be activated for all users on a computer?

A personal licenseis licensed to a single person; only this person is permitted to use PTGui. For this reason a personal license is activated for a single user account on the computer only. For more information see Q1.5.

A company licenseis licensed per computer, and PTGui may be used by any person on that computer. Therefore the company license can be activated for all users on a computer.

To do so, ensure that all users have read and write permissions to this folder: C:\ProgramData\PTGui\(Windows) or /Users/Shared/Application Support/PTGui/(macOS). Activation data will be stored in a file named reg.dat in this folder. When activating PTGui with a company license key, and the above folder can be written to, PTGui will ask whether the license should be activated for all users PTGui Pro mac Archives the computer. Answer Yes to do so. If PTGui was already activated for a PTGui Pro mac Archives user, first deactivate the software via Help - License Info - Deactivate. Then re-activate the software by entering the license key after ensuring all users have write permissions to the above folder.

3. General questions


3.1. Is PTGui or the documentation available in other languages?

Yes, PTGui and its documentation are available in English, PTGui Pro mac Archives, Deutsch, Nederlands, Español, Français, Português, 日本語, 한국어 and 中文. The language can be selected in Options/Preferences.

3.2. My lens database is empty, is that normal?

Yes, it is. You can use it to store your optimized lens data.

3.3. Can PTGui work with 16-bit images from start to finish (ie, no 8-bit conversion)?

Yes, PTGui performs all image processing in 16 bit if a 16 bit output format is selected on the Create Panorama tab. PTGui Pro even supports 32 bit floating point images.

3.4. Can I use PTGui to create virtual tours?

PTGui includes a viewer for publishing panoramas on a website. See Q6.15for more information.

The web viewer included with PTGui is just a basic viewer for publishing individual panoramas. For a true virtual tour consisting of multiple panoramas linked by hotspots, clickable floor plans, etc, dedicated panorama publishing software exists. All panorama publishing software can load panoramas in 360 x 180 degree equirectangular projection, as created by PTGui. See Q6.15for software recommendations.

3.5. Sensor sizes: millimeters vs inches?

To determine the lens projection, PTGui needs to know the dimensions (in millimeters) of the camera's sensor. Some manufacturers state the sensor size in fractions of an inch (e.g. 1/2.5"). The inch-designation dates back to TV camera tubes in the 50s and it does not appear to be mathematically related to the actual sensor size. See Table of sensor formats and sizes(Wikipedia) for a conversion table.

3.6. My images were taken with a (e.g.) 28mm lens, but after optimization, PTGui reports it as a 31.5mm lens

This is normal; the optimizer adjusts your project in such a way that the lowest control point distance is obtained. By default this involves modifying the focal length of the lens. PTGui Pro mac Archives it is at this focal length that PTGui achieves the best alignment of the images, PTGui Pro mac Archives.

3.7. Can PTGui read RAW/DNG files?

Yes, PTGui uses LibRawwhich allows it to read RAW files produced by many cameras.

Note that RAW files are not regular image files, PTGui Pro mac Archives. WinISO 6.4.1 Registration Code + Serial Key Crack Download 2021 RAW file records the data straight from the camera's sensor, which needs to be demosaicedand processed further before it can be used. Therefore RAW files should rather be seen as a digital 'negative' which first needs to be developed to get the actual image.

This development is done using standard settings, although PTGui Pro does allow you to adjust exposure and white balance in the HDR/Exposure tab.

If you need more control, use a dedicated RAW converter instead and save the converted RAW files as 16 bit TIFF images. The TIFF files can then be loaded into PTGui. This preserves the image quality and full dynamic range of the source images. Be sure to convert all source images in a panorama using the same settings, otherwise color or brightness differences may remain visible in the panorama.

Also, any adjustments made to the RAW file in Photoshop RAW (or other RAW converters) are ignored by PTGui, PTGui Pro mac Archives. These programs do not actually change the RAW file; instead they write the modifications to a so-called sidecar (.xmp) file. The sidecar file contains closed proprietary data and cannot be read by other software. Therefore, if you need to make changes to RAW file or need finer control over the conversion, use a dedicated raw converter and save the images to 16 bit TIFF format.

Finally, since all RAW files are different it's possible that LibRaw does not (yet) support your camera. PTGui Pro mac Archives that case it's also necessary to convert your images to TIFF before loading them into PTGui.

3.8. Will PTGui read RAW files from camera XXX?

PTGui uses the open source LibRaw library for decoding raw files. See Supported Cameras on the LibRaw websitefor a list of cameras supported by LibRaw. PTGui can only read raw files supported by LibRaw. If LibRaw does not support your camera, use a dedicated raw converter to convert the images to 16 bit TIFF.

See Q3.7for more information.

3.9. What does 'Apply Template' do?

This copies the settings of another project to the current project, except for the images and the control points. This function is accessible both from the 'Apply Template' item in the File menu, and from the toolbar in PTGui. A template can be any PTGui project. In Tools/Options/Folders&Files, a folder can be configured where you store your templates (on Mac go to the PTGui menu, Preferences, PTGui Pro mac Archives, Folders&Files). The template selection dialog will by default open in this folder, PTGui Pro mac Archives. The 'Apply Template' button on the toolbar shows a drop down list of all templates in the configured template directory, for quick access.

Templates can be useful for a quick initialization of a project (lens settings, rough alignment of images), although this is usually not necessary since the Project Assistant can figure out the alignment of the panorama by itself, PTGui Pro mac Archives.

Another use for templates is when you have an exact reproducable setup (high quality panoramic head with fixed angles). In this case you could copy all settings of a previous project and there would be no need for placing control points and optimizing.

By default, applying a template copies all settings from the template to the current project except for the source images and the control points. In PTGui Pro this behavior can be modified in the Project Settings tab, section 'template behavior'.

3.10. Apply Template does not copy the control points from the template. Why is that?

By default applying a template copies all settings from the template except for the actual source images and the control points (see Q3.9). Control points are never copied since they are specific to the source images. For example a control point could originally point to the corner of a building in the template project, but in another project the same coordinates may be in the middle of plain blue sky. In other words the control points are meaningless outside the context of the original images.

If you just need a project to be stitched exactly like the template project, control points are not needed at all. Control points are only used by the optimizer to determine the best image parameters. The stitcher only uses the optimized image parameters and ignores the control points. Therefore it's sufficient to apply the template (which copies the image parameters) and proceed straight to Create Panorama without running the optimizer.

3.11. What kind of computer hardware do you recommend for use with PTGui Pro mac Archives does not require any special hardware, even for stitching large panoramas. But if you're looking for high performance we recommend a PC with the following specifications:

  • RAM: 16 GB or more. RAM is relatively cheap these days and data in RAM can be accessed at least 100x faster than data stored on disk. For gigapixel panoramas or HDR panoramas consider getting 64 GB or more.
  • Disk: this should be an SSD, not a spinning hard drive. Especially when stitching large gigapixel panoramas, using an SSD for temporary storage will give a huge reduction in stitching time. If you must use external disks, connect them through USB 3 or thunderbolt; USB 2 is too slow. NVME internal SSDs will give the best performance. You can configure which drive PTGui uses for temporary storage in Options/Preferences (in the Folders & Files tab).
  • GPU: PTGui features OpenCL hardware acceleration, reducing stitching time significantly. Basically any current AMD or NVIDIA graphics card of $300 or more will be fine. See Q8.2 for more information.
  • Processor: PTGui is multi threaded so it will run faster on processors having more cores. With GPU acceleration enabled, much of the processing will be offloaded to the GPU, but the 'zero offset' blending algorithm and automatic seam placement are not GPU accelerated. Therefore a faster processor will somewhat improve the stitching speed.

3.12. Does PTGui preserve the metadata of my images?

Currently, the following metadata is copied to the generated panorama:
  • EXIF: Original date and shooting date of the first image in the panorama, Author, Copyright info, GPS data, Camera make / model
  • XMP metadata: Generally all XMP metadata is copied, PTGui Pro mac Archives for metadata specific to the source image but not applicable to the panorama. For example metadata concerning focal length or the image size is not copied to the panorama, but replaced with appropriate values for the stitched image.
  • Exposure data: exposure time, aperture and ISO sensitivity (only if identical for all source images)
  • ICC Color Profile (for the selected output color space)
  • For equirectangular panoramas: Google Photosphere Metadata, PTGui Pro mac Archives, so that other applications will recognize the image as a spherical panorama.
  • For rectilinear panos, PTGui also adds the FocalLength and FocalLengthIn35mm tag, corresponding to the field of view of the stitched panorama. In other words, the focal length that would give the same view on a full frame camera.
For HDR panoramas Clion 2019.1 license key Archives PTGui Pro, the 'blend planes' output contains the exposure/iso/aperture of that particular exposure, for merging in external software.

Other EXIF data is currently not copied to the output file. The above metadata is written to JPEG, PTGui Pro mac Archives, TIFF, psd and psb images. For .hdr no metadata is written. The .exr format does not support EXIF or XMP metadata and PTGui only includes the exposure information. The color profile is read and written in the .exr specific 'chromaticities' tag. But note that this is not widely supported. Many other applications (including Photoshop) ignore this entirely, and assume all .exr files have a linear sRgb color profile.

3.13. Can I stitch images from a shift lens with PTGui?

First of all, you don't need a shift lens if you have PTGui! Shift lenses are often used for architectural photographs: photographing a building from ground level, while tilting the camera upwards, normally results in converging vertical lines. Shift lenses compensate for this effect by shifting the optical axis of the lens relative to the center of the image plane. The result is a photograph where parallel lines remain parallel.

The same effect can be achieved in PTGui: open the Panorama Editor window, press Ctrl-P to switch to 'Panorama Edit' mode. Now drag the panorama upwards or downwards until parallel lines in the scene are parallel in the panorama. You may need to increase the vertical field of view (using the slider to the right of the panorama).

If you do want to stitch images taken with a shift lens in PTGui, change the following parameters:
  • Switch to Advanced mode by pressing the Advanced button in the side bar
  • In the Lens Settings tab, select 'Individual Shift Parameters' for all images for which the lens was shifted
  • Run PTGui Pro mac Archives optimizer by pressing F5
Regardless whether a shift lens is used, or the panorama was shifted in the Panorama Editor, PTGui Pro mac Archives will end up with some black space below or above the panorama. This can be removed by dragging yellow crop lines from the edges of the panorama in the panorama editor. PTGui Pro mac Archives process is shown in detail in part two of our Video Tutorial.

3.14. Where does PTGui store its settings?

PTGui stores its configuration data in this folder:

Windows:
%APPDATA%\PTGui\
macOS:
~/Library/Application Support/PTGui/
To open this folder, do Tools - Open Folder - PTGui Configuration Folder in PTGui. Most configuration data is stored in Configuration.xml in this folder. The default folders for Templates and Batch Lists also reside here.

3.15. PTGui doesn't fully use my computer's processor(s); the CPU load is less than 100% during stitching

Stitching and blending requires a lot of disk and memory access. In particular for large panoramas, or on multi core computers, not the processor but the hard disk may be the speed limiting factor. Also, with a suitable graphics card much of the processing is offloaded to the GPU. If you are looking into increasing stitching speed, see Q3.11, PTGui Pro mac Archives.

3.16. After optimizing, PTGui shows me the average control point distance. What distance should I aim for?

The control point distance indicates how well a control point pair aligns in the panorama. When the distance is zero, the two points of a control point pair overlap exactly.

One should aim for the lowest control point distance possible, but the actual lowest distance that can be achieved depends on many factors. In general if your images were shot properly using a tripod with calibrated panorama PTGui Pro mac Archives, a control point distance well below 5 should be achievable, PTGui Pro mac Archives. Most remaining misalignments can usually be masked by the blender. An average distance higher than 5 usually indicates a problem, see Q5.4for solutions.

It's particularly important to look at 'outliers': if a control point has a distance of 20 while the average is below 5, this control point might have been placed on a moving object, PTGui Pro mac Archives, or on a similar feature close to the proper location. Use the 'Delete worst control points' function (in the Control Points menu) to remove such outlying control points.

3.17. Why does PTGui Pro close my project and open a new blank project after I press Save and Send to Batch Stitcher?

The Batch Stitcher of PTGui Pro can generate control points; it will do so if instructed by the 'Do Align Images and save the modified project' checkbox in the Project Settings. By default this is enabled if the control point generator has not yet been run for the project. This allows you to quickly generate a panorama in batch: start a new project, load your source images and press Save and Send to Batch Stitcher. The batch stitcher generates control points and stitches the panorama in one go.

After generating control points and aligning the images the batch stitcher overwrites the project file with the modified version. Since the Batch Stitcher will modify the project 360 Total Security 10.8.0.1371 Premium License Key, problems could occur if the project would remain opened at the same time in the main PTGui Pro window: both instances would be writing to the same project file, discarding each other's changes.

For this reason, PTGui Pro will close the project after sending it to the batch stitcher if the Batch Stitcher is configured to modify the project. This ensures that only one instance of the project is open. A warning message is shown before the project is closed but the warning is no longer shown if 'don't show this again' had been selected. To re-enable the warning message, go to Options/Preferences and click 'Reset all warning messages'.

In previous version of PTGui, a temporary copy of the project would be sent to the batch stitcher. This functionality is still available through 'Send Temporary Copy to Batch ProtonVPN 1.12.0 keygen Archives. This creates a copy of the current state of the project in a temporary file, which is sent to the batch stitcher for stitching. When stitching has finished the temporary project file is deleted by the batch stitcher.

3.18, PTGui Pro mac Archives. PTGui asks me whether I would like to re-initialize the project. What does this mean?

If PTGui fails to properly align your images, PTGui Pro mac Archives, the following question may appear:

"The optimizer failed to achieve a good alignment of the images. Possibly the current misalignment of the images causes the optimizer to get stuck. Re-initialization of the project may help in such a case. Would you like to re-initialize the project and try to optimize again?"

If you click OK, PTGui will reset the yaw, roll and pitch of all images to zero and reinitialize the lens settings based on the EXIF data. Then it will attempt to figure out the image positions from scratch and subsequently reoptimize the project.

In particular in cases where the optimizer got stuck in a so-called local minimum such an initialization from scratch can be the solution.

This function can be triggered manually using the Initialize and Optimize (in the Project menu).

3.19. Can PTGui create those interactive photos where the camera is rotated around the object?

These are commonly called 'Object Movies'; they cannot be created through stitching and therefore PTGui does not support this. A software package for creating object movies is Object2VR.

3.20, PTGui Pro mac Archives. After stitching a project in the PTGui Pro Batch Stitcher, the project is modified!

The batch stitcher of PTGui Pro can not only stitch projects, but it can also set up a new panorama project by generating control points, aligning the images, etc. It will do so if instructed by the 'Do Align Images and save the modified project' checkbox in the Project Settings tab. If the project or template is already set up completely and the panorama should only be stitched, make sure that the above checkbox is unchecked.

3.21. I have edited my RAW / DNG files in Photoshop or another application. Does PTGui recognize my changes when I PTGui Pro mac Archives the raw files in PTGui?

No, PTGui will load the raw files as they came straight from the camera, any modifications are ignored. In Photoshop RAW files can be edited, but the changes are written to a 'side car' file (with the .xmp extension) rather than to the original raw file. The settings in the side car file are specific to the algorithms used by Photoshop and cannot be used by other applications.

To use the modified RAW files in PTGui Pro mac Archives, export them to 16 bit TIFF files and load those in PTGui instead. Since RAW files typically only have 12 or 14 bits per channel, the full dynamic range will be preserved by the 16 bit TIFF file, so there is no loss of quality.

3.22. What can I do to reduce the stitching time PTGui on my system?

The time required to stitch a panorama is influenced by many factors, such as the dimensions of the panorama, the computer hardware and by other applications running at the same time. Some general hints to improve the stitching performance:
  • First of all, stitching time depends mostly on the output size of the panorama. The size of the source images also has a slight influence. Render the panorama at a smaller size to reduce stitching time.
  • PTGui is slow in loading RAW and DNG images. For best performance convert your raw images to 16 bit TIFF format.
  • Disable Optimum Seam placement (PTGui Pro, see the Blending side bar in the Panorama Editor) if speed is important. Calculating the optimum seams will take time.
  • Stitching to 16 bit output will generate twice as much data as when stitching to 8 bit output, PTGui Pro mac Archives, and thus take longer.
  • External blending plugins such as Smartblend may get slow for larger panoramas. Try the built in blender of PTGui instead.
  • Memory usage of PTGui can be configured with the following setting in Tools-Options-Advanced (Windows) or PTGui-Preferences-Advanced (Mac):
    Use at most . MB of RAM memory: PTGui will attempt to stitch the panorama in RAM as much as possible, but once the panorama is too large to fit entirely in RAM, temporary data will get written to disk. This setting determines the maximum amount of RAM that will be used. There is an optimum value: if PTGui has access to little RAM it will start to use the hard disk for temporary storage earlier, which is much slower. But if PTGui attempts to use too much RAM it will attempt to 'steal' RAM from other applications. The operating system will start swapping applications to and from disk if the total needed amount of RAM exceeds the amount available. This can bring the entire computer to a crawl. Therefore this setting should be chosen as high as possible, but such that no swapping occurs. Other memory intensive applications should be closed while PTGui is stitching.
    Finding the optimum values for these settings is a matter of trial and error.
  • Adding more RAM memory, a fast hard disk or an OpenCL capable graphics card can improve stitching speed. See Q3.11 for hardware recommendations.

3.23. I have moved or rotated images in the Panorama Editor by hand using the Edit Individual Images mode, PTGui Pro mac Archives. But PTGui tells me it needs to optimize the panorama and this undoes my PTGui Pro mac Archives. Why?

Don't attempt to align images manually: it's impossible to get the required precision for a seamless stitch. Even if you would manage to accurately align an image to one neighbouring image, this would throw it out of alignment with its other neighbour images.

Instead, let the PTGui optimizer do all the hard work through control points. Control points tell PTGui which points of two images should overlap. By providing 3 or 4 control point for a pair of overlapping images, PTGui will know how they overlap and the optimizer will align the images with pixel accuracy.

For more information watch our our Video Tutorial.

3.24. Can PTGui stitch greyscale images?

PTGui was designed to efficiently stitch RGB color images (with or without transparency). It can read single channel greyscale TIFF files but the output will always be in RGB format. If you require single channel greyscale TIFF files as output, PTGui Pro mac Archives, use third party software such as Photoshop to convert the output to the desired format.

3.25. PTGui keeps Folder Lock 7.8.6 Crack With Registration Key the output size in the Create Panorama tab. Why?

By default (the Create Panorama tab will show 'fix at 100% of optimum size'), PTGui will output your panorama at the so called Optimum Size. The optimum size is the output size at which the resolution of the panorama equals the resolution of the source images. For more information see Q3.26.

Because the optimum size depends on several parameters, including the focal length of the lens which is usually fine tuned by the PTGui Pro mac Archives, the optimum size may vary slightly after each optimization. This depends also on control point placement. If this fluctuation is unwanted, in the Create Panorama tab pick a desired size and select 'Fix at . megapixels'. From now on PTGui will keep the number of pixels in the panorama constant.

3.26. How does PTGui calculate the optimum output size of a panorama?

The optimum size is the output size at which the resolution of the panorama equals the resolution of the source images. In other words, no detail from the source images is lost.

Because image warping is not uniform across the panorama, there is no true optimum size: some parts of the source images may get enlarged while other parts may be reduced in size. Therefore, somewhat arbitrarily, PTGui considers the optimum size to be the size where the angular resolution of the center of the source images equals the angular resolution of the center of the panorama. If images from multiple lenses are used, this calculation will be based on the source image having the highest resolution.

Because the optimum size depends on several parameters which are adjusted by the optimizer, the optimum size may vary slightly for different projects using the same lens. See Q3.25.

3.27. Why does PTGui 11 use a different optimum size than PTGui 10?

In PTGui 11 a new lens parameter, the 'fisheye factor' was introduced (see Q3.28). This allows it to perfectly CATIA R2021X Crack + Torrent! all practical fisheye projections. PTGui 10 didn't include this parameter and used equidistant projection for all fisheye images. The difference between the actual projection and equidistant projection was modeled using the lens distortion (a/b/c) coefficients. When calculating the optimum size, the lens distortion coefficients are not taken into account, resulting in an error in the calculated optimum size. PTGui 11 does take the fisheye factor into account when calculating the optimum size.

In other words, the optimum size is calculated more accurately in PTGui 11 than in PTGui 10, PTGui Pro mac Archives. Regardless, it's still a somewhat arbitrary measure (see Q3.26) and it's possible to output at any desired size.

3.28. What exactly does the Fisheye Factor parameter do?

There is no single fisheye projection, different fisheye lenses exhibit different PTGui Pro mac Archives projections. For example, equidistant, equisolid or orthographic fisheye lenses exist. For more information see Fisheye Projection (PanoTools wiki), PTGui Pro mac Archives. Visually, these projections differ by the amount of compression or stretching of the image near the edge of the fisheye circle. PTGui up to version 10 simply modeled every fisheye lens using the equidistant projection. The deviation of the actual projection from equidistant projection was compensated for by using the a/b/c lens distortion correction polynomial. This worked, but with caveats: because the relation between focal length and field of view differs for each kind of projection, PTGui could misestimate the size of the cropping circle for circular fisheye lenses. And secondly, the control point generator would have more difficulty finding control points (especially near the edges of the image) if the wrong fisheye projection was used.

In PTGui 11 this was solved by introducing the Fisheye Factor parameter. Fisheye lenses are now modeled using the following formula:



Here, kis the fisheye factor, fis the focal length, θis the angle of the light ray entering the lens and Ris the radial distance from the image center of the projected light ray.

By varying the fisheye factor kthe equation morphs into the different fisheye projections. Values of the fisheye factor for the common PTGui Pro mac Archives are:

Equidistant: k= 0
Stereographic: k= 0.5
Orthographic: k= -1.0
Equisolid: k= -0.5
Rectilinear (non-fisheye): k= 1.0

In normal use of PTGui the fisheye factor is initialized to the known value of the lens before running Align Images. PTGui knows the fisheye factor for many common models of fisheye lenses. If EXIF data is available PTGui can often recognize the brand and model of the fisheye lens automatically, and set the fisheye factor accordingly. If no EXIF data is available, the brand and model of the fisheye lens can be selected from a list. In practise no lens follows the above projection model exactly, therefore a/b/c lens distortion correction is used to compensate for any remaining small differences between the ideal and actual projection.

The fisheye factor of a lens can be determined by the PTGui optimizer. When optimizing the fisheye factor, care must be taken to avoid interference by the a/b/c lens distortion correction parameters: in the Lens Settings tab, press the PTGui Pro mac Archives button to reset a/b/c to zero, PTGui Pro mac Archives. Then in the Optimizer tab, enable optization of the fisheye factor and disable optimization of a/b/c. As always, for accurate optimization of the lens parameters, images without parallax should be used.

3.29. Can I install different versions of PTGui side by side?

Yes, this is possible. Any version (trial, Pro, beta) can be installed in parallel to your current version of PTGui. In Windows, the installer will ask you for an installation folder (e.g. C:\Program Files\PTGui) and a Start Menu folder. If you enter different folder names, your current version will not be overwritten. On Mac, PTGui is distributed in a disk image (.dmg file). Double click the .dmg file to mount it. Inside there's the PTGui application. Drag the application to the desktop, then rename the application. Finally move the application from the Desktop into the Applications folder.

PTGui project files will by default be opened in the last installed version. To change this under Windows: right click on a PTGui project file, at 'Opens With' click on Change, click 'More Apps', click 'Look for another app on this PC', then browse (under Program Files) to the particular version of PTGui to use.

On macOS: ctrl+click on a PTGui project file, select 'Open With', 'Other.', select the PTGui application to use, enable 'Always Open With' and click Open.

Keep in mind that the settings and license information are shared by all PTGui applications for the current user.

If you accidentally overwrote your licensed version of PTGui with a trial version, you can re-download your licensed version even if it was an older version; see Q1.8.

3.30. I've upgraded from PTGui 11 to PTGui 12 and now my panoramas look different.

Many new features have been added to PTGui 12: automatic optimum seam placement, a new 'zero overlap' blending algorithm, color management and a new HDR processing workflow. Internally all processing is now done on linearized floating point pixel data. A new Post Processing side bar was added to the panorama editor for adjusting the toning curve and image saturation. The toning curve is now applied to raw files, which would look somewhat dull in PTGui 11. Color management ensures that out-of-gamut colors and clipped highlights after stitching and blending are properly handled.

We've tried hard to retain compatibility with PTGui 11, but all these changes mean that your stitched panorama may look somewhat different in PTGui 12 than in PTGui 11. First of all, if you are simply stitching properly manually exposed TIFF or JPG files, not using HDR, PTGui hardly needs to adjust anything to the images, PTGui Pro mac Archives. The output will look very similar to the source images in terms of color and contrast, both in PTGui 11 and 12. But tone mapping, exposure fusion and raw conversion are subjective processes, and any changes we make here will have side effects, both positive and negative. A slight increase in the default contrast for example may be an improvement to one user for one specific panorama, but considered a degradation in another case. Default settings can be changed though!

If you're just looking to get the same results as in PTGui 11 without any hassle: PTGui 11 is still available for download, see: Q1.8. You can even install PTGui 11 and 12 side by side on the same computer and run them at the same time: Q3.29, PTGui Pro mac Archives. We've taken care to keep project files backwards and forward compatible as much as possible.

Automatic seam placement in PTGui Pro 12 means that the seams will be placed entirely different from PTGui 11. Generally this will make stitching errors less noticeable, but as a side effect objects may suddenly appear in the PTGui 12 panorama which would be hidden in the PTGui 11 panorama. It's possible for example that PTGui 12 decides to show the tripod in the nadir of the panorama if this is considered to result in the optimum seam placement, PTGui Pro mac Archives. This may happen even if a separate nadir image without tripod is available. PTGui is not PTGui Pro mac Archives enough to understand that the tripod is something you don't want to show in the panorama. The solution is to mask any unwanted objects using red masks in the Mask tab. Just a coarse mask or a couple of red dots is sufficient: PTGui understands the mask is part of something that should be removed and it will attempt to route the seams around the entire object.

Also, automatic seam placement will cause the outer part of the PTGui Pro mac Archives images to be used more, whereas PTGui 11 would simply place the seams in the middle of the overlap area, PTGui Pro mac Archives, as far away as possible from the edges of all source images. Some lenses at wider aperture have better PTGui Pro mac Archives quality in the center, and PTGui 12 may decide to use some of the worse parts of the source image. Again, seam placement can be adjusted by adding green or red masks.

And of course automatic seam placement can be disabled entirely by disabling 'Find Optimum Seams' in the Blending side bar of the panorama editor. You'll also find a 'precision' slider there: moving this slider to the right will cause PTGui to calculate the seams at a higher resolution, PTGui Pro mac Archives. But be careful, at the highest 1/1 setting it will take several minutes, or even hours, and use much memory. And the seams must be recalculated after every change to the panorama.

Another thing that's changed in PTGui 12 is the PTGui Pro mac Archives. The new Zero Overlap blending algorithm works very well in combination with optimum seam placement. Because it doesn't use any overlap it will give seamless results even if the seam is routed just very close around an object. The traditional multiband blending algorithm needs a certain amount of overlap and will cause the excluded object to still appear as a faint 'ghost' image if it is close to the seam. In general, PTGui Pro mac Archives, Zero Overlap blending can also cope better with moving clouds and waves in water and it better handles exposure differences, PTGui Pro mac Archives. But it may have trouble with finely patterned surfaces like ceilings or carpets. Also if a seam cuts through a moving object this may be more visible than with multiband blending. You can switch between Zero Overlap and Multiband in the Blending side bar to compare the results.

If you just want to have the same blending as with PTGui 11: disable 'Find Optimum Seams' and choose 'Blender: Multiband'.

Handling of raw files was improved (in our opinion), but if you prefer the less contrasty look of PTGui 11, go to the Post Process tab in the panorama editor and reduce the 'Shape' and 'Shift' sliders of the Toning Curve closer to zero. Fine adjustments to the slider can be made by holding down the Shift key while dragging the slider. Settings can be saved to a file or to a template. And keep in mind that PTGui does not intend to replace a dedicated raw converter: images will definitely look better when you convert your raw files in Photoshop, PTGui Pro mac Archives, Lightroom or another raw converter (see Q3.7).

The new Toning Curve is also applied as part of exposure fusion and tone mapping, PTGui Pro mac Archives. The Post Processing tab replaces the Contrast and Saturation settings that were previously available in the Tone Mapping settings. If the tone mapped panorama is not to your taste, PTGui Pro mac Archives, adjusting the Toning Curve or Saturation sliders in the PTGui Pro mac Archives Process tab may improve this. The response of the Sigma parameter (for Exposure Fusion) has slightly changed, again the advise is to experiment with the settings until the result is to your taste.

If all fails there's still the option of outputting a 32 bit .exr file, or blend planes, from PTGui 12 and load this into PTGui 11 (or in a third party application) for tone mapping.

Handling of bracketed images has changed in PTGui Pro 12. In PTGui Pro 11 it was possible to stitch an HDR panorama from bracketed images without linking the images, PTGui Pro mac Archives. In PTGui Pro 12, linking bracketed images is mandatory! Linking is required for getting optimum seam placement to work: when creating blend planes, the seams must be placed in the same location in each blend plane. To calculate the seams, PTGui must know which images belong to the same bracketed set, and you tell this by linking the bracketed images. If the images were taken by using the camera's auto bracketing, they will follow a repeating exposure pattern. PTGui will recognize PTGui Pro mac Archives and offer to link the images when running Align Images. You can also force PTGui to link the images by selecting Images -> Link HDR Bracketed Exposures. If PTGui reports that no bracketed sets were detected, this means that the exposure pattern is not repeating in exactly the same way for each bracketed set. You can still link images manually: go to the Source Images tab, select a group of images, right click and choose 'Link Selected Images'. Repeat this for all bracketed sets.

Not linking bracketed exposures will lead to unexpected results in PTGui 12: the automatic optimum seam placement may decide to include or exclude entire images, because the same area is covered by multiple overlapping (bracketed!) images. Zero overlap blending will cause the excluded images not to be used at all. And optimizing or otherwise editing the panorama may completely change the seams, PTGui Pro mac Archives, causing entirely different source images to be flipped into the panorama even when making just minor changes. Again, do Images -> Link HDR Bracketed Exposures to make sure that the images are linked.

Even though images have to be linked, it's still possible to use hand held bracketed images. When linking the images, just tell PTGui that the images were not taken from a tripod. The images will get independent yaw/pitch/roll coordinates even though they are linked. There's a new 'Link' checkbox in the Image Parameters tab to configure this for each set of bracketed image separately.

3.31. I've upgraded from PTGui 11 to PTGui 12 but stitching is much slower now!

PTGui Pro 12 performs automatic optimum seam placement. Calculating the best location of a seam among millions of pixels takes considerable processing time. It's also something that cannot CleanMyPC Crack 2021 With Activation Code Full Version Free Download be done in parallel: using a different starting point may result in a completely different optimum seam. Seam placement has a cascading effect: changing the seam at one side of the panorama may eventually affect the position of another seam at the opposite side. This cascading means that the seams have to be calculated sequentially and the process therefore cannot make efficient use of multiple CPU cores or the GPU.

If optimum seam placement is not desired, it can be disabled in the Blending side bar and the panorama will be stitched much faster. Switching to Multiband blending will speed up stitching even more, PTGui Pro mac Archives, the new Zero Overlap blending is somewhat slower.

3.32. Does PTGui use cube faces internally as part of the stitching process?

No, when stitching source images into a spherical panorama, PTGui projects the images directly into the selected output projection (equirectangular generally). An intermediate cube face representation is not used.

3.33. What kind of tiles does the PTGui Viewer use internally?

The PTGui Viewer uses a custom 14 face polyhedron as the internal representation.

3.34. When was PTGui first released?

The first (beta) version of PTGui was released10th of July 2000. Originally PTGui was a front end PTGui Pro mac Archives Helmut Dersch's Panorama Tools library. Even though PTGui has improved much over the years, and PTGui Pro mac Archives is not using Panorama Tools anymore, the workflow is still similar. Even the first beta version was already capable of stitching spherical panoramas.

4. Troubleshooting


4.1. I am trying to edit the seams of a layered panorama in Photoshop, PTGui Pro mac Archives, but I only see the bottom layer with the merged panorama; the other layers are transparent.

This is by design, PTGui Pro mac Archives. The idea is to use the blended panorama as the basis for retouching, selectively revealing parts of the source images for retouching by making the masks opaque.

4.2. Another application crashes when opening TIFF files generated by PTGui, or it displays garbled images.

TIFF is a container format which can contain many different types of image data; almost no application supports all possible TIFF formats, PTGui Pro mac Archives. PTGui can create 16 or 32 bit TIFF files and TIFF files with an alpha channel but these features are not supported by many applications. If you need create a compatible TIFF file, press the 'Settings' button in the Create Panorama tab, and choose: 8 bits, no alpha channel and no compression. The resulting file can be opened in nearly every application that supports TIFF files. Also keep in mind that not all TIFF capable applications can read BigTIFF images, so they will fail to open TIFF files larger than 4GB.

4.3, PTGui Pro mac Archives. My computer crashes occasionally while PTGui is running

A normal application like PTGui (i.e. not a driver or a kernel process) is unable to crash an entire computer; the worst that could normally happen is the application itself crashing but not the entire computer.

If the computer crashes, shows a 'blue screen' error or spontaneously reboots this is usually indicating a problem with the hardware or a driver. It's possible that you observe the problem only when running PTGui: stitching large panoramas places a heavy load on the processor, hard disk and memory. This could trigger any existing hardware problems for example due to the increased temperature of the processor, due to increased load on the power supply, or simply because any existing problem is more likely to be PTGui Pro mac Archives when the system is used intensively.

If you however observe crashes in PTGui but the operating system continues to run properly then this could be a bug in PTGui. The Windows version of PTGui includes a crash reporter; we encourage you to submit the crash data to us for analysis. Mac users please send the crash report to us at support at ptgui dotcom; crash reports on the Mac can be found in <User>/Library/Logs/CrashReporter/.

4.4. PTGui shows a message 'PTGui was unable to detect control points for some of the images, PTGui Pro mac Archives, therefore you need to add a few control points by hand'. Help! What should I do now?

When you press Align Images, PTGui analyzes your source images and looks for details which can be seen in multiple images. For example, the corner of a building might be visible in the right hand side of one image and in the left hand side of another image. On these matching details PTGui places so called Control Points. To see what control points look like, go to the Control Points tab in PTGui after you have run Align Images. In the Control Poins tab select two overlapping images by clicking the thumbnails above the images and you will see numbered markers indicating the matching features. Ultimately the control points are used by PTGui to set up the panorama: it warps and moves the images in such a way that the control points match as closely as possible.

If you see the above message, this means that PTGui was not able to find control points for all images. The human eye is still better in recognizing patterns than a computer and in this case you will need to help PTGui a bit. To do so, first open the Control Point Assistant (in the Tools menu). The PTGui Pro mac Archives Point Assistant will tell you what the problem is, for example 'Image 4 does not have any control points'.

Besides single images lacking control points it's also possible that there are clusters of images linked by control points: for example image 1,2 and 3 are linked by control points and image 4,5 and 6 are linked by control points, but there are no control points between images in either cluster. To create a panorama all images should directly or indirectly be linked by control points, so in this example adding control points between image 3 and 4 would OctoPlus Box v2.9.6 crack Archives the problem.

Suppose the Control Point assistant tells you that image 4 does not have control points: go to the Control Points tab in the main window, and choose image 4 in the left pane, PTGui Pro mac Archives. In the right pane find an image which partially overlaps image 4 (most likely image 3 or image 5). Find an object which is visible in both images, click on that object in the left image and click on the same object in the right hand image, PTGui Pro mac Archives. As you see a colored marker has been added. Repeat this until you have added at least 3 control points, PTGui Pro mac Archives. Then go back to the Control Point Assistant and see if there are any other images that need control points.

When done, go back to the Project Assistant tab in the main window: the above error message is now gone. As the last step the project needs to be optimized: click on the blue underlined link to do this. The optimizer will re-align the images such that the control points match as closely as possible. Verify the result in the Panorama Editor window: the panorama should now be set up properly.

The above workflow is shown in detail in our Video Tutorial.

Sometimes an image contains no recognizable details at all (for example if the images contains pure blue sky only). In that PTGui Pro mac Archives see Q6.28.

For more information use the on line help available for the Control Points tab and the Control Point Assistant window: in most screens you can get context help by pressing F1 (Windows) or Fn+F1 (Mac).

4.5. PTGui is randomly rotating my images!

The orientation of the images the main window is synchronized with the orientation of the images in the stitched panorama. For example, if you rotate an image in the Panorama Editor 90 degrees clockwise, the image thumbnail in the Project Assistant will be rotated clockwise as well. And if you rotate the entire panorama 90 degrees, PTGui Pro mac Archives, all images in the Project Assistant will be rotated too.

If PTGui seems to randomly rotate your images PTGui Pro mac Archives running Align Images, most likely it was unable to properly align the panorama, resulting in misaligned and randomly rotated images in the Panorama Editor. It may seem that the misalignments are caused by the random rotation but it is in fact the other way round: due to the misalignments the images get randomly rotated in the panorama, and the orientation PTGui Pro mac Archives the images in the Project Assistant simply reflect the orientation of the images in the panorama.

Also see Q6.44.

4.6, PTGui Pro mac Archives. I'm having trouble stitching my panorama. Can you help?

First of all, if you are new to PTGui check out our Video Tutorial. It may help you understand what the problem might be. In particular make sure that all images are taken from exactly the same viewpoint and that the camera is rotated around the entrance pupil of the lens (which is usually close to the front of the lens). In general a regular tripod is not suitable for taking panoramas; you need a dedicated panoramic head to ensure that the camera is rotated around the front of the lens and not around the tripod screw.

If this does not solve the issue please post your panorama to the PTGui support forumand we'll be happy to take a look. Large files cannot be uploaded to the forum directly; instead create a zip file with your panorama and upload it to a file publishing site such as wetransfer, Dropbox or Google Drive, PTGui Pro mac Archives. Then include the URL of the uploaded file in your forum post. To allow us to help you quickly, upload at least the PTGui project file (.pts). Depending on the problem we may need the image files as well.

4.7. After editing a 360 degree panorama in Photoshop and importing back into PTGui, I'm seeing a vertical line in the panorama

This is caused by the fact that Photoshop isn't aware that the left and right edge of the image wrap around. When doing local adjustments (in particular contrast enhancement) near one of the edges, pixels at the other edge should also be taken into account, otherwise a hard edge will be visible when the panorama is later wrapped around in a panorama viewer.

You can work around this limitation in Photoshop by extending the panorama: a section from the right hand side of the panorama is pasted next to the left hand side, and vice versa. Subsequent adjustments will then take properly into account the pixels 'over the edge'. When done editing, reduce the panorama to the original size.

We've created a set of Photoshop scripts to accomplish this with a single mouse click: download PhotoshopExtendCanvas.zip. Please see readme.txt inside the zip file for installation instructions.

4.8. When installing on a Mac I get the error "PTGui Pro cannot be opened because PTGui Pro mac Archives identity of the developer cannot be confirmed. macOS cannot verify that this app is free from malware."

This may happen when installing older versions of PTGui on newer versions of macOS. Apple has locked down macOS to only allow running signed applications. Over the years Apple has changed the requirements for signing multiple times. The current PTGui version has the proper signatures but older PTGui versions will be rejected by macOS.

The signature verification can be bypassed as follows: Ctrl+click on the PTGui application, select 'Open'. In the subsequent warning window, click 'Open'.

4.9, PTGui Pro mac Archives. I'm unable to open a QuickTime VR .mov panorama

QuickTime VR (or QTVR) was a special dialect in the QuickTime .mov video format supporting interactive playback of spherical panoramas. For many years this has been the format of choice for embedding panoramas in web pages: the QuickTime plugin was installed on every Mac and on many Windows computers (it was included with iTunes for Windows). With the introduction of QuickTime X in 2009, Apple has dropped support for QTVR panoramas. These days HTML5 is the format of choice for displaying panoramas on web pages (see Q6.15).

QTVR panoramas can still be viewed by installing QuickTime 7, but be aware that this creates a security risk: exploits for QuickTime 7 exist and Apple is no longer updating the software. That said:
Installing QuickTime Player 7 on your Mac
Download QuickTime 7 for Windows.
Windows users can alternatively use the DevalVR player (Unicode)which can also play back QTVR panoramas.

Pano2VRcan be used to convert an existing QTVR .mov file to another format.

4.10. I'm attempting to stitch images taken with multiple cameras but I'm running into stitching errors

Seamless PTGui Pro mac Archives stitching requires that all images are taken from exactly the same viewpoint. Moving the viewpoint causes parallax which makes it impossible to stitch images perfectly. For more information about parallax see Q5.4and watch the Video Tutorial.

This requirement is very critical: even photos taken from viewpoints spaced only a few centimeters can have significant parallax, causing clearly visible stitching errors on nearby objects. When taking panoramas with a single camera parallax should be avoided by using a panoramic tripod head: this ensures that the camera is rotated around the 'no parallax point' which is usually located near the front of the lens.

When using multiple cameras, parallax is unavoidable which means that it is simply impossible to stitch the images perfectly. This problem is particularly apparent in panoramic video because this can only be created from multiple cameras. The only real 'solution' is to lower your expectations and accept that stitching errors will be visible. That said, for the best results consider the following:
  • Try to mount the cameras as closely as possible to reduce the parallax
  • The effect of parallax diminishes as objects get further away from the camera. If there's an object close to the camera try to make sure it is captured entirely in one of the images, instead of having a seam run through it.
  • Making a stitching template for panoramic video is generally best done using images taken in a wide open space, PTGui Pro mac Archives, placing control points only on distant objects (which don't have much parallax due to the distance). This ensures that PTGui is able to correctly estimate the lens parameters. While you may be able to somewhat improve the stitching of a particular scene by adding extra control points on a nearby object, this will in fact degrade the stitching of other frames where the object or the camera has moved, so don't do this when creating a stitching template.
  • Enabling 'Find Optimum Seams' (in the Blending side bar of the panorama editor) can help to hide misalignments caused by parallax. On the other hand it is not keyscape free crack Archives for stitching panoramic video or time lapse series: the PTGui Pro mac Archives will flip to different locations in each subsequent frame.

4.11. My panoramas stitched using a template in the Batch Builder have misalignments. This only happens in the Batch Builder; the panorama is perfect if I use the same template in the GUI.

Essentally there are two different use cases for the batch builder:
  1. To stitch Taxact 2005 crack serial keygen panoramas using the exact same settings, PTGui Pro mac Archives, without generating control points. This can be used for example with multi camera rigs, where all panoramas are guaranteed to have the same image orientations.
  2. or to automatically stitch a number of panoramas by just pointing PTGui to a folder with images. The images are taken for example by rotating the camera on a panoramic tripod head.
In the latter case the image positions in each panoramas will usually be slightly different. Even if the panoramic head has click stops, mechanical tolerances will cause small variations in the image orientations in each panorama. To compensate for this PTGui should analyze the images for each panorama and generate control points.

Whether the batch stitcher will generate control points is controlled by this setting in the project:
Project Settings -> Batch Stitcher actions -> Do 'Align Images' and save the modified project
This option should be checked in the template used in the Batch Builder, unless the image positions in each panorama will be absolutely identical.

4.12. The Batch Builder seems to ignore the settings in my template; my panoramas come out different than expected.

If you are using a multi camera rig and need all panoramas to be stitched absolutely identically, uncheck this setting in your template:
Project Settings -> Batch Stitcher actions -> Do 'Align Images' and save the modified project
Also see Q4.11.

If you do require PTGui to generate control points but would like to keep the panorama size and projection as set in the template, see: Q6.24.

4.13. The panorama in the PTGui Viewer is full of black dots!

This is a known issue caused by a bug in Intel's graphics driver, PTGui Pro mac Archives. It's affecting the PTGui Viewer only, the stitched panorama from PTGui should be fine. The problem seems to be limited to Windows computers with dual graphics processors (both a low power Intel integrated GPU and a more powerful AMD or NVIDIA discrete GPU). The problem can be solved by updating the Intel graphics driver. For laptops a driver package is usually made available on the laptop manufacturer's website. Look for the driver package including the Intel graphics driver.

If a driver update is not possible, PTGui Pro mac Archives, the problem can be solved by telling Windows 10 to always use the AMD or NVIDIA graphics (and not Intel's integrated graphics) for the PTGui Viewer:
  • Open the Windows 10 Settings app by pressing the Windows key + i
  • Click on System
  • Click on Display
  • Scroll to the bottom and select 'Graphics settings'
  • Under 'Graphics performance preference' select 'Classic app'
  • Click Browse and browse to the PTGui Viewer application: C:\Program Files\PTGui\PTGuiViewer.exe
  • The PTGui Viewer is now listed in the Graphics Settings window. Click its Options button, PTGui Pro mac Archives, select 'High performance' and click Save
Another alternative is PTGui Pro mac Archives use FSPViewer (which doesn't use OpenGL) instead of the PTGui Viewer. See Q6.29.

4.14. I'm using PTGui 10; the stitching process hangs and never completes.

This may happen on Windows machines with NVIDIA graphics hardware. Recently NVIDIA have released a driver update for Windows which appears to break GPU acceleration in PTGui 10. The problem does not seem to affect PTGui 11 and later.

If you don't wish to upgrade to PTGui 11, you may do one of the following:
  • Disable GPU acceleration in PTGui (see Options - Advanced)
  • Or downgrade the GPU driver to an earlier version. NVidia's driver version 397.64 is known to work. To download older nvidia drivers see: NVIDIA advanced driver search. But please understand that security problems may have been fixed in later drivers. Running older driver versions may be a security risk.

4.15. Panoramas published using Publish to Website are not displayed correctly using Firefox, the image is flashing.

This problem occurs with older versions of the PTGui web viewer on recent versions of Firefox. It is fixed in the current version of the PTGui Viewer. Web pages created with Publish to Website in PTGui 11.28 should not exhibit the problem.

For panoramas created with earlier versions the problem can be fixed by updating PTGuiViewer.js on your web server. Download the latest PTGui Viewer hereand replace PTGuiViewer.js on the web server with the latest version. Right-clicking in the panorama on the website should show 'PTGui Viewer version 2.6' (or newer). If you still see the old version, clear the browser cache or append a random query string to the url in the html page like this: <script src="PTGuiViewer.js?random=2878342342">This will force the web browser to use the new version.

4.16. The brightness or contrast in the Detail Viewer differs from the stitched panorama!

This is a known limitation of the Detail Viewer when using Tone Mapping or Exposure Fusion. Tone Mapping and Exposure Fusion make local contrast adjustments to the image. Adjustments in a particular area are influenced by the image contents surrounding that area. For example, if the sun is visible in the panorama, Tone Mapping and Exposure Fusion will PTGui Pro mac Archives the areas in the sun's neighborhood.

This means that to properly apply Tone Mapping or Exposure Fusion, the panorama must be processed as a whole. But the the Detail Viewer only sees a part of the panorama. Suppose the sun is just outside the visible area of the detail viewer, and then the Detail Viewer's orientation is moved until the sun becomes visible, PTGui Pro mac Archives. This will completely change the tone mapped image.

In other words, Tone Mapping and Exposure Fusion in the Detail Viewer offer just an approximation. The actual result can be seen in the Panorama Editor. A quick preview can be generated by pressing the 'eye' toolbar button in the Panorama Editor, or through the Preview Tab in the main window.

4.17. I'm getting an error message "These images cannot be linked because they have different dimensions. Linked images should have the same pixel dimensions." Why?

You may see this message when linking bracketed exposures for HDR. Usually the images will have the same number of pixels but the problem is caused by different image orientations (portrait vs. landscape) within the bracketed set. In general PTGui can deal with mixed image orientations, except when working with bracketed images. Linked images must have the same dimensions and orientation.

Image orientation can be encoded in the image in two different ways: the image may be physically rotated in a specific orientation, PTGui Pro mac Archives, but it's also possible that the rotation of the images is encoded using the EXIF 'Orientation' tag. In the latter case, portrait and landscape images may actually be stored in the same physical orientation (usually landscape), and they will only differ in their Orientation tag. In this case the problem can be worked around by telling PTGui to ignore PTGui Pro mac Archives orientation tag:
  • Start a new empty PTGui Project (required because the following setting cannot be changed once the images are loaded)
  • Go to the Project Settings tab, Miscellaneous section, and uncheck the following: 'Physically rotate images with EXIF Orientation tag upon loading'
  • Now load your images and proceed.
Note that the Project Settings tab is available only in the Pro version of PTGui 11 and earlier, PTGui Pro mac Archives. Starting with PTGui 12, Project Settings will be available in the standard Edraw Max 9.4.1 full version Archives as well.

If the images are physically rotated differently, the above solution will not work and the problem can only be solved by rotating the images in an external image editing program before loading in PTGui.

Again, note that this limitation only applies to images within a bracketed set. Usually the problem happens when shooting bracketed nadir images: when the camera is pointing down, the orientation of the image (portrait or landscape) is ambigious. But we think a camera should use the same orientation for each group of bracketed images, it shouldn't randomly rotate images in a bracketed set. Tell your camera manufacturer that PTGui thinks this is a bug.

For many cameras the automatic orientation sensor can be switched off; this is recommended when shooting panoramas, PTGui Pro mac Archives.

4.18. One of the source PTGui Pro mac Archives is not included in the blended panorama. Why is that?

Since version 12, PTGui Pro performs automatic optimum seam placement. If an image is entirely overlapped by other images, the seams may be placed such that the image does not get used at all in the blended panorama. The panorama is fully covered by all other images.

The seam finder attempts to route seams around objects, so the object will either be included or removed completely. But PTGui can't know if the object is something you want to keep or exclude. So for example it's possible that the tripod remains visible in the nadir even if you added an additional nadir image, with the tripod removed, PTGui Pro mac Archives, to cover it.

You can tell PTGui Pro to use a particular image by adding a green mask in the Mask tab. Often a small dot of green mask is sufficient; the optimum seam finder will enlarge the area such that the seams will be the least noticeable.

It's also possible to disable optimum seam finding altogether in the Blending side bar of the panorama editor.

4.19. The image in the Detail Viewer looks different from the final panorama. I'm using exposure fusion / tone mapping.

The Detail Viewer only shows a small section of the panorama. But generating an accurate preview of the tone mapping or exposure fusion can only be done by rendering the entire panorama. So the preview in the Detail Viewer is inaccurate when using exposure fusion / tone mapping. To get an accurate preview, go to the Preview tab in the main window, create a preview of the entire panorama and PTGui Pro mac Archives it in the PTGui Viewer.

Tone mapping PTGui Pro mac Archives exposure fusion perform local contrast adjustments to the image. The adjustments to part of the image will influenced by the surrounding image content. For example, PTGui Pro mac Archives, if the Sun is visible in the panorama, PTGui Pro mac Archives, it's brightness will influence the tone mapped (or exposure fused) image around it. If the Detail Viewer shows a part of the panorama not containing the sun, the sun's bright pixels will not be taken into account, so the preview will not be an accurate representation of the full tone mapped panorama.

4.20. PTGui is dislaying OpenCL errors, or the computer crashes while running PTGui on a Windows computer with NVIDIA graphics.

For GPU acceleration to work reliably on NVIDIA GPUs it's important to run their latest so called 'Studio Driver'. NVIDIA also offer a 'Game Ready' driver but this is known to cause crashing or even blue screen reboots on Windows. See NVIDIA Driver Downloads.

Running other GPU accelerated applications (Lightroom, Capture One, etc) while stitching panoramas will also cause problems.

If all fails, there's always the option of disabling GPU acceleration in Options - Advanced. PTGui will run fine without GPU acceleration, just slower.

5. Improving the results


5.1. The horizon of my panorama is curved instead of straight

See Tutorial: straightening a panorama

5.2. I get color/brightness differences between the images in my panorama

First of all always make sure to lock the exposure and white balance of your camera. Color differences can be corrected to a certain amount by the blending process, but you will get the best results by locking the color balance and exposure when shooting the images.

Exposure is locked by choosing the M mode if your camera. To lock white balance, choose one of the white balance presets on your camera that match the current lighting, such as 'Cloudy' or 'Sunny'.

Even with color balance and exposure locked you may still see get small differences in brightness due to vignetting. PTGui can correct for this, see Vignetting correction with PTGui.

5.3. How can PTGui Pro mac Archives change the resolution (ppi or dpi value) of the generated panorama?

This can be changed in the Metadata tab. Switch to Advanced mode to reveal this tab.

Be aware though that the resolution of an image has nothing to do with image quality or print quality. The ppi/dpi value of an image file is just a number embedded in the header of the file, suggesting the number of pixels to be printed in one inch. You could set the resolution to a very large dpi value but this will not modify the image in any way, except that the image would be printed smaller (and thus have more pixels per inch).

The number of pixels is what really matters: if you need a more detailed output image, increase the width and height of the output image instead (on the Create Panorama tab). Click the '100%' button PTGui Pro mac Archives the Create Panorama tab to achieve the highest quality. Increasing the output size beyond the optimum size is possible but will only increase the file size, not the amount of visible detail, since the latter is limited by the (angular) resolution of the source images.

Also see: The Myth of DPI.

5.4. I see misalignments in the stitched panorama. What can I do to improve the result?

Parallax: First of all, make sure that the photographs are taken properly: for panoramas, all images should be taken from exactly the same viewpoint. More in particular: the camera should be rotated around the 'no parallax point' (sometimes referred to as the 'nodal point') of the lens. For most lenses this point is located near the front element; since it does not coincide with the tripod screw of the camera, you will need to use a so called panoramic head. If the camera is not rotated exactly around this point, parallax errors will occur, PTGui Pro mac Archives, preventing a perfect stitch. Don't attempt to take PTGui Pro mac Archives panorama from a tripod without using a panoramic head, you'll get serious stitching errors.

In about 4 out of 5 support questions we receive regarding stitching problems, parallax turns out to be the reason for the problem. Therefore for an introduction to parallax please read these articles: Finding the no-parallax point(by John Houghton) or What is parallax?(PanoGuide). Be sure to also watch our Video Tutorial: parallax is explained in the first video.

Florian Knorn made an in depth video tutorial on calibrating a panoramic head.

For experienced PTGui users, in Finding the nodal point(PDF), Frank Cullmann shows an alternative method for finding the no-parallax point by analyzing control point distances in PTGui.

The impact of parallax errors differs per scene: for a landscape panorama, with no objects close to the camera, a limited amount of parallax might not be a problem and such a panorama can easily be taken handheld. But for panoramas of room interiors even a small misplacement of the camera of just one centimeter or inch will result in clearly visible stitching faults, PTGui Pro mac Archives. Creating a good interior panorama is therefore impossible without using a tripod and properly calibrated panoramic head.

In contrast to (e.g.) barrel distortion, correcting for parallax faults in software is impossible. This PTGui Pro mac Archives not a limitation of PTGui but a physical limitation. If you must stitch images with parallax, the best you can do is to mask the faults after stitching by placing the seams appropriately (see our post processing tutorial) but PTGui Pro mac Archives can be a lot of work and often does not lead to perfect results. Parallax problems lead to overall high control point distances: if you have many control points with an optimized distance of 20 or more (see below), this usually indicates a parallax problem.

Misplaced control pointscan be another reason for misalignment. Especially if there are repeating structures in the images, the control point generator may occasionally misplace one or two control points. The same can happen if there are moving objects in the panorama: slowly moving clouds in the sky are notorious in particular (also see Q6.42). Finding these misplaced control points is easy: open the Control Point table (Ctrl+B on Windows or Cmd+B on Mac) and find the control points with the largest distance. This distance indicates the alignment error of the control point in the panorama. By default, the table is #1 Video Converter 3.4.9 crack serial keygen in descending distance, so the worst aligned control points are in the top of the list. In general, a distance below 5 is sufficient, while higher values usually indicate a problem. Double click on a control point in the table to edit it, or delete it by pressing Del.

Misalignment in an area of a panorama can occur if there are no control points in that particular area, PTGui Pro mac Archives. Go to the Control Points tab and add a few points in problem areas to improve the alignment there.

A common misconception is that using a wide angle lens would cause misalignments, due to the distortion inherent to wide lenses. This is not true: PTGui can perfectly correct perspective distortion and barrel distortion in wide angle lenses. A panorama from a wide angle lens will thus look exactly the same as the same scene taken PTGui Pro mac Archives a long lens, apart from any differences in quality and resolution.

5.5. Some control points in my project have a relatively high control point distance. Will the alignment of my panorama improve if I delete all control points with an error above a certain threshold?

No, not necessarily. When editing control points you should not just aim for the lowest possible control point error. Instead the goal should be to keep all control points that are placed correctly, and delete only the faulty ones. Faulty control points include for example points placed on moving objects such as people, clouds and cars, PTGui Pro mac Archives, and control points placed incorrectly on different objects. The latter may happen in particular with repeating structures.

Often these misplaced control points have a higher than average control point error, but the reverse is not true: not every control point with high error is a faulty one. If you have a control point pair with a large error but with both markers placed on the same spot on a non-moving part of the panorama, then this control point actually improves the alignment of that particular area in the panorama. Therefore it should be kept rather than deleted, even though this increases the average control point distance.

If you are consistenly getting control points with high errors (say, 5 or higher) then this most likely means that your images suffer from parallax. Only images without parallax can be stitched perfectly. See Q5.4for more about parallax.

5.6. My drone panoramas are showing misalignments at the horizon. How can I get a straight horizon?

Ultimately these errors are caused by parallax: if the camera has been moved between taking the first and last images, foreground objects will have shifted relatively to background objects. If control points are placed on nearby objects, PTGui will attempt to align those objects but stitching errors will result on objects far away (i.e. anything on the horizon).

In drone panoramas usually the misalignment will be most severe between the first image and the last image in the sequence, due to the drone drifting over time. Especially altitude drifting will lead to clearly visible stitching errors at the horizon, because a vertical misalignment at the horizon is extremely noticable.

One workaround for parallax is to remove all control points on nearby objects and only keep control points on objects further away from the camera. This effectively removes the parallax and results in a perfectly straight horizon, PTGui Pro mac Archives. But this will come at the expense of stitching errors on foreground objects. Those stitching errors would need to be retouched manually.

Often a better alternative is to use Viewpoint Correction on all images except one. Viewpoint Correction is available in the Pro version of PTGui. Although Viewpoint Correction is intended to be used on flat surfaces only, it can work quite well on drone images even UMT Dongle 6.3 Crack Archives the surface is not actually flat.

Proceed as follows:
  • Load all images and run Align Images
  • Make sure all images have control points; if not, PTGui Pro mac Archives, add control points where necessary
  • Switch to Advanced mode PTGui Pro mac Archives pressing the Advanced button in the side bar
  • Go to the Optimizer tab
  • Switch the Optimizer to Advanced mode by pressing the Advanced button in the Optimizer tab
  • Enable Viewpoint Correction for all images except one image. This can be done by clicking the header above the 'Viewpoint' column: all cells of the 'Viewpoint' column will be selected. Then left-click in one of the cells and select 'Optimize'; this should change all cells to 'Optimize'. Now click and hold down the mouse button for one second in a cell of the Viewpoint column, PTGui Pro mac Archives, so that only that cell is selected and change this cell to 'Reset'. A good candidate is an image in which the horizon is visible and not obstructed by nearby buildings.
  • Run the Optimizer. It will assign viewpoint offsets to the images.
  • Do Control Points - Generate Control Points. This will generate extra control points fitting the viewpoint optimized images.
  • Do Control Points - Remove Worst Control Points. If the parallax was not too severe to start with, it would now report a 'good' optimization result.
  • Add a couple of 'Horizontal Line' control points on the horizon. Part #8 of the Video Tutorial series shows how to do this. Although the tutorial covers Vertical Line control points, the procedure for adding Horizontal Line control points is the same. Run the Optimizer again to level the panorama.
Usually this will result in a well aligned panorama with a straight horizon. Keep in mind though that Viewpoint Correction may result in slanted (i.e. non-upright) buildings. This is not very noticable if the parallax was caused by altitude differences, but if the drone moved sideways you may see nearby high rise buildings leaning slightly to one side.

Also, when optimizing Viewpoint, it's important to keep at least one image without Viewpoint Correction. The corrections in other images will be 'anchored' to this image. If viewpoint optimization would be enabled for all images, the optimizer is given too much freedom and may distort all images extremely in order to minimize the misalignments, PTGui Pro mac Archives. Therefore one of the cells in the 'Viewpoint' column in the Optimizer tab should be set to 'Reset'.

6. How to.


6.1. My panorama contains curved lines. How do I get straight lines to remain straight in the panorama?

You would need to use the PTGui Pro mac Archives panorama projection. Rectilinear projection is the only projection that preserves all straight lines; all other projections will curve certain lines. Unfortunately rectilinear projection is limited in practise to a maximum field of view of about 120 degrees, so there is no way to preserve straight lines for wide panoramic scenes in a single image. This is not a limitation in PTGui but a physical limitation.

For more information see: Projections

But by using an interactive panorama viewer it's possible to show a wide panorama while preserving straight lines: the panorama viewer only renders a narrow rectilinear view in a certain viewing direction. The user can look around in the entire scene by changing the viewing direction. See Q6.15and Q6.29.

6.2. How do I use the Horizontal line and Vertical line control points?

See part #8 of our Video Tutorialseries.
Also, John Houghton wrote an excellent tutorial.
German readers see this pageby Bernhard Vogl

6.3. How can I calibrate my lens parameters?

For panoramic stitching you don't need to know the lens parameters since PTGui calibrates your lens automatically for each panorama. But knowing the lens parameters can be useful if you (for example) would like to correct a single image for barrel distortion. The lens parameters can be calibrated accurately as follows:
  1. Take enough images to build a 360 degree, single row panorama. Make sure the images overlap by at least 30%. Make sure that the camera is rotated around the 'no parallax point' of the lens, in order to avoid parallax errors.
  2. Load the images into PTGui, and execute step 2 (Align Images) of the Project Assistant.
  3. Switch to the Control Points tab and review all generated control points. Remove any misplaced control points, and any control points on moving objects (including clouds in the sky!). Also remove any control points on nearby objects, since these will suffer the most from any remaining parallax errors in your setup. Make sure that each pair of overlapping images has at least 4 control points (more is better). Ensure that there are some control points PTGui Pro mac Archives the corners of the images as well, not just in the center.
  4. Optimize the project using the Optimize button in the Project Assistant.
  5. Open the Control Point table (Ctrl+B or Cmd+B). The control point distances should be small, generally less than 3. If you find control points with higher distances, correct or remove them by repeating the previous two steps.
  6. Switch to Advanced mode by pressing the Advanced button in BUSTAFELLOWS Free Download side bar.
Now the optimized lens parameters can be found as the a, b and c parameters on the Lens Settings tab. Use the Lens Database button to save the values for later use.

Please note that different orientations (landscape vs. portrait) and different focal lengths (in case of zoom lenses) will result in different correction values, so be sure to save separate entries in the lens database for each zoom setting and for landscape and portrait orientation. Even at the same zoom setting and orientation subsequent calibrations may result in significantly different a/b/c values. This is normal, since completely different a/b/c values may represent very similar lens correction curves.

6.4, PTGui Pro mac Archives. Does PTgui allow stitching of photos that have the camera in different locations?

In general this is not possible. PTGui was designed for stitching true panoramas, by taking overlapping photos from a single camera viewpoint. If the camera is moved between shots, parallax errors will occur. Correcting for parallax errors in software is physically impossible so in general it is impossible to stitch such images without visible misalignments.

There is one exception: if the subject to be photographed is flat, like a wall or like aerial photographs (shot from some altitude and without high rise buildings), parallax faults will not be noticable, PTGui Pro mac Archives. Such images can be stitched in PTGui if the following conditions are met:
  • the subject should be flat, or if the subject is not completely flat, all control points should PTGui Pro mac Archives be placed on a flat surface only. When stitching aerial photographs, remove any control points that are not on the ground surface. When stitching photos of a wall or facades of buildings in a street, remove all control points on any objects in front of the surface.
  • the camera should be pointed exactly perpendicular to the subject's surface, i.e. for aerial images the camera should be pointed exactly vertically
  • in all shots the camera is at exactly the same distance from the surface
Under these circumstances the photos can be stitched using the process for stitching mosaics, see the section directly below.

If the subject to be photographed is not too wide and the camera can be placed at sufficient distance, consider taking your photographs as a true panorama instead, from a single camera viewpoint. Choose a rectilinear panorama projection so that straight lines in the scene will remain straight in the panorama. The result will probably look better than when attempting to stitch images where the camera was moved between shots.

6.5, PTGui Pro mac Archives. How can I stitch mosaics, like partial scans from a flatbad scanner of a large image?

PTGui was designed for stitching panoramas from photographs taken from a single camera viewpoint. When stitching a panorama, images are warped to correct for perspective distortion so that a seamless overlap is achieved. For mosaic-style stitching on the other hand the images should only be shifted and rotated; any perspective warping is undesirable. PTGui can be tricked to do no warping by setting the focal length to a very large value. When stitching images taken with a very long lens from a large distance, no perspective warping is needed, only transformation and rotation. This is similar to stitching mosaics.

So to stitch mosaics, proceed as follows:
  • Start a new project and load your source images
  • Switch PTGui to Advanced mode using the Advanced button in the side bar
  • Go to the Lens Settings tab and set the Lens type to Rectilinear, PTGui Pro mac Archives. Set the Focal Length to a high value (e.g. 1000mm).
  • In the Control Points menu choose 'Generate Control Points'
  • Go to the Optimizer tab. Deselect the 'Optimize lens focal length' checkbox. At 'Minimize lens distortion', choose 'Heavy'.
  • Press the Run Optimizer button (at the bottom)
  • Now go to the Panorama Editor window by pressing Ctrl+E (Windows) or Command+E (Mac). First press the PTGui Pro mac Archives Panorama button, then press the Fit Panorama button.
Your mosaic is now ready to be stitched at the Create Panorama tab.

6.6. My panorama was taken with the camera tilted up or down. Now there's a lot of unnecessary black space above/below the panorama, increasing the size of the output. Can it be cropped away before stitching?

Yes, this is possible. Although the field of view sliders in the panorama editor always crop the panorama in a symmetrical way (keeping the horizon of the panorama in the middle), an alternative way to crop the panorama is by using the yellow crop lines which can be dragged from the corner of the image in the panorama editor. An example of this is shown on page 4 of the Quick Tour. The crop lines can be placed anywhere so this method is not restricted to symmetrical cropping.

6.7. How can I have better control of the overlap area (i.e. the location of the seams)?

The easiest way to achieve this is by using the Masking features in PTGui Pro. See the Video tutorial(part 6).

It's also possible to retouch a panorama in Photoshop after stitching, by using a layered output format; see the (old) Post processing tutorial.

6.8, PTGui Pro mac Archives. How can I create a vertical panorama? PTGui rotates my panorama 90 degrees!

For single row panoramas, PTGui will always attempt to align the images in a horizontal row. This behavior cannot be changed, but you can easily rotate the panorama: in the Panorama Editor, simply use the right mouse button and drag the panorama to the right orientation. After rotating, you may need to press 'Fit Panorama' in the Panorama Editor to resize the panorama area so that it fits.

Vertical panoramas usually look best in one of the Transverse projections. You can choose a suitable projection in the Projection submenu of the Panorama Editor menu.

6.9. I want to cover the tripod in my (360x180 degree) spherical panorama. How do I add a nadir cap?

There are several options. Peter Nyfeler has created a Photoshop action for adding a mirror ball nadir cap.

Or you could use your own logo. The logo needs to be warped into the projection of the panorama, PTGui Pro mac Archives, as follows:
  • Start a new PTGui project
  • Add your logo image to the project
  • Switch PTGui to Advanced mode
  • Go to Lens Parameters and select 'Rectilinear' and (e.g.) 60 degrees field of view, PTGui Pro mac Archives. The value you enter here sets the size of the warped logo.
  • Panorama Settings: Equirectangular, 360x180 field of view
  • Image Parameters: set the Pitch angle of the image to -90 degrees
  • It's not necessary to add control points or to optimize
  • Create Panorama tab:
    Width/Height: same as your original spherical panorama
    Output format: .psd Subscribe to Blog via Email .tif
    Layers: blended panorama only
  • Then press 'Create Panorama'
The result is a warped version of your logo. Overlaying the logo has to be done manually in a graphics editing program. A quick way to do this in Photoshop is by selecting the entire logo image (Ctrl-A), copying it (Ctrl-C) and then pasting it into the panoramic image (Ctrl-V). This creates a new layer in the panorama with the logo.

If you have PTGui Pro, instead of covering the missing parts consider using Viewpoint Correction to create a full panorama of the entire scene including the nadir. See the Viewpoint correction tutorial.

6.10. How can I change the default settings for new panoramas?

Choose 'Make Default' in the file menu to save the current settings as a starting point for new projects, PTGui Pro mac Archives. This will save all settings, except for the images and control points. It works exacly like Apply Template but it is applied to every new project.

Even if you changed the defaults, the Project Assistant will still override certain settings in order to ensure a good result: it will adjust the field of view of the panorama to fit the contents and it will choose a suitable projection depending on the field of view. All of this can be overridden as follows (Pro version only):

  • First of all do: File - Reset Default Project Settings, to remove any modified default settings
  • File - New Project
  • Click on Advanced
  • Go to the Project Settings tab and disable these checkboxes:
    • Fit Panorama
    • Choose a suitable projection
  • Go to the Panorama Editor
  • Select the desired panorama projection and field of view. For example Panorama Editor - Projection - Preset - Spherical (360 x 180 degree equirectangular)
  • Go to the Create Panorama tab and select the desired output size and file format. After changing the size it should be set to 'fix at . megapixels'.
  • Now either do File - Save As Template to create a template: this template should be applied before pressing Align Images, or the template can be used in the Batch Builder.
    Or do File - Make Default if these settings should be used for all future projects.

6.11. How can I stitch extremely large panoramas?

If you have enough free disk space and a fast computer, PTGui can PTGui Pro mac Archives stitch hundreds or even thousands of images into a panorama. Not all file formats can be used though:
  • JPEG: maximum size is 65,535 x 65,535 pixels. Keep in mind that some applications cannot open JPEG files wider or taller than 30000 pixels.
  • TIFF: unlimited dimensions, PTGui Pro mac Archives. Traditional TIFF is limited to files of 4GB in size. PTGui supports the BigTIFF dialect which does not have this limitation, PTGui Pro mac Archives. PTGui will automatically switch to BigTIFF when the file size exceeds 4GB. Keep in mind that not every TIFF capable application is able to read BigTIFF.
  • Photoshop .psd: max 30,000 x 30,000 pixels and a maximum file size of 4 GB
  • Photoshop .psb: no limitations in practise. Photoshop has a limit of 300,000 x 300,000 pixels. PTGui can create panoramas larger than this but Photoshop will not be able to open them.

6.12. How can I align a set of images, all taken in the same direction (not a panorama)?

This can be done using PTGui; it can be used for (e.g.) accurately aligning a set of images for manual HDR creation, for making a time lapse movie, or for extending depth of field by merging images taken at different focusing distance.

It requires a special workflow though. By default, PTGui expects that a project contains overlapping source images, taken from the same viewpoint, but in different directions. The perspective changes that occur when the camera is rotated allow PTGui to accurately calculate the focal length (or field of view) of the lens. When all images are taken in the same direction, this information is missing and PTGui may end up optimizing the RevisionFX ReelSmart Motion Blur 4.0 crack serial keygen parameters to wrong values. This can result in a very small field of view, or introduce barrel distortion.

If the images are taken in one direction, they can be aligned in the following way:
  1. Load the source images in PTGui.
  2. Switch to Advanced mode by pressing the Advanced button in the side bar.
  3. If the goal is to combine PTGui Pro mac Archives images into a single HDR or tone mapped image, the images should be linked, PTGui Pro mac Archives. To do so, PTGui Pro mac Archives, go to the source images tab in PTGui Pro. Select all images, right click and choose 'Link Selected Images'. This ensures that the images will be merged to HDR instead of being blended as a regular panorama. Next, go to the Image Parameter tab and uncheck the 'Link' checkbox for all images. This ensures that PTGui is creating control points between the bracketed images in order to align them.
  4. Go to the Optimizer tab, uncheck 'Optimize PTGui Pro mac Archives focal length' and choose 'Minimize lens distortion: No'.
  5. In the menu bar, choose Control Points Apply Template and select the template created above. The images are aligned already and the panorama can be stitched by going straight to Create Panorama.

    The template can also be used for batch conversion using the Batch Builder (PTGui Pro only):
