Download PTGui 11.8

A frequently discussed piece of software in the Photo & Video Workflow subforum is PTGui. This program focuses on stitching panoramic photos on both macOS and Windows systems. With a stack of photos as input, the program can figure out how to put them next to each other. For the computation-intensive part, it can also use the gpu via OpenCL to be ready faster. It features various options, where PTGui Pro also makes it possible to combine HDR photos, mask moving objects and adjust the viewing point, among other things. Version 11.8 was released a few days ago with the following changes:

Version 11.8

• Fix: Windows: occasional crashing
• Fix: Mac: under macOS 10.14, when using GPU acceleration, lines could be visible in the stitched panorama. This is probably caused by a bug in the macOS OpenCL runtime. To workaround this problem, for part of the blending process the CPU is used instead of the GPU. This solves the problem, but GPU accelerated stitching will be somewhat slower.

Version 11.7

• PTGui has been translated and can now run in multiple languages: English, Deutsch, Nederlands, Español, Français, Português, 日本語, 한국어 and 中文. The language can be selected in Options/Preferences.
• Added lens profile for GoPro Hero 5 Black
• Support for dual fisheye images from Ricoh Theta V and Insta 360 One X
• Added sensor sizes for several new cameras
• Typing a custom size in the Create Panorama tab now switches the output size mode to ‘fixed at … megapixels’, so the custom size will stick when running the optimizer
• Delete Worst Control points works much better now. This also causes better rejection of control points on moving objects (eg clouds)
• Performance improvements in panorama editor and detail viewer when using GPU acceleration
• Improved resilience against crashing OpenCL drivers. If the OpenCL driver crashes it should now be possible to start PTGui with GPU acceleration disabled.
• If the output folder for the panorama does not exist, it will be created automatically when stitching the panorama
• Batch Stitcher: new function File | Append Batch List. This adds all projects from the selected Batch List to the currently active Batch List.
• Batch Builder: if the batch stitcher is still busy stitching the previous Batch List when sending another Batch List to the Batch Stitcher, it will now offer to append the new batch list instead of replacing the active batch list.
• Fixed: Lens database associations for GoPro cameras were ignored
• Fixed: When tone mapping LDR panoramas containing some black areas, the tone mapped panorama could be completely black.
• Fixed: Importing a PTGui 10 project containing individual lens parameters (circular fisheye) would result in the wrong lens parameters being assigned
• Fixed: Under some circumstances, straight lines near the center of a wide angle fisheye image could become curved
• Fixed: Fill Yaw (right click in Image Parameters table) didn’t function correctly
• Fixed: Batch Builder: if the ‘one subfolder per camera’ configuration was used, the images in the generated projects would be sorted by the file names. This could result in unexpected swapping of images. Images are now sorted by the name of the containing folder.
• Fixed: File name suffixes for cube face filenames (as set in Tools – Convert to Cubic) were not preserved across restarts
• Fixed: Windows: crash when loading corrupted jpeg files
• Fixed: When editing and re-saving images in another application while they are loaded in PTGui, PTGui could pop up an error message about corrupt or empty files. PTGui will now wait until the image is saved completely by the other application.
• Fixed: PTGui would use ‘circular fisheye’ for the tokina 10-17 at 10mm, while it could use fullframe fisheye
• Fixed: For large panoramas PTGui would create too large temporary files (up to 2 TB each), wasting temporary disk space when stitching large panoramas.
• Fixed: Windows: crash if the drive containing temporary files is disconnected while PTGui is running (eg in case of an external USB drive)
• Fixed: Assertion Failed error when optimizing lens flare in the Exposure/HDR tab.
• Fixed: PTGui failed to read certain LZW compressed TIFF files
• Fixed: PTGui Viewer would display a garbled panorama if the image was not a 2:1 360×180 image
• Fixed: Stitching a project on the command line using ‘-stitchnogui’ would fail if a relative path name was given
• Fixed: Stitching a Batch List on the command line using ‘-stitchnogui’ would fail randomly
