Software Update: PTGui 12.8

A frequently discussed piece of software in the Photo & Video Workflow subforum is PTGui. This program focuses on creating and adjusting composite images. This can be a vertical or horizontal panorama, but also one large image with an enormous resolution that is composed of countless individual shots. Using a stack of photos as input, the program can figure out how to put them side by side on both macOS and Windows computers. For the computation-intensive part, the GPU can also be used 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. The following changes and improvements have been made in this release:

Changes in version 12.8:

• Added lens data for TTArtisan 7.5mm F2 fisheye.
• Added ACEScg and ACES2065-1 presets for Output Color Space in the Create Panorama tab.
• If Exposure/HDR -> Settings -> Camera Response Curve is set to Automatic (the default), PTGui will only optimize the camera curve if the project consists of linked bracketed images. Previously it would optimize the curve if the project contained different exposures (not necessarily brackets) but this lead to problems if tonemapped Av images were used. The default behavior can be overridden by explicitly selecting ‘Generate new’.
• On Windows 11 buttons now have rounded corners.
• Fixed a bug that could cause PTGui to crash occasionally.
• Fixed: possible blending artifacts when outputting at larger than optimum size.
• Fixed: seams in the rendered panorama could be different from the preview when using Multiband blending.
• Fixed: errors could pop up if a calibrated display profile was used under windows.
• Fixed: The ‘Masking pushes back seams’ setting would be changed after saving and loading the project, or when applying a template.
• Fixed: On some linux installations PTGui would incorrectly say ‘OpenCL is not available on your computer’.
• Fixed: PTGui would refuse to load certain images with corrupt EXIF ​​GPS data. It will now load the image and ignore malformed GPS data.
• Fixed: PTGui web viewer: if the fullscreen button was not shown, double tapping would still switch to fullscreen.
• Fixed: PTGui web viewer: PTGuiViewer.js would capture mouseup events without propagating them to the containing web page. This could cause other elements in the web page to malfunction.
