Download PTGui 12.23

A regularly 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 separate shots. With a stack of photos as input, the program can then figure out how to place them next to each other. For the calculation-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 version 12.23:

Changes in version 12.23:

• PTGui would fail to load certain DNG files, giving the error message 'Unknown error'
• Support added for Kandao QooCam 3.
• Fixed: PTGui when launched with the -stitchnogui flag could display an error message 'invalid lock file'
• Fixed: PTGui when launched with the -stitchnogui flag could (incorrectly) show a popup 'It appears that PTGui previously crashed while using OpenCL for GPU acceleration.'
• Fixed: if 'Optimize Brightness' was enabled in the automatic exposure and color adjustment settings (in the Exposure/HDR tab), the brightness optimization could behave erratic, resulting in very dark images.
• Fixed: subtle color banding artifacts could appear in the output if multiband blending was used and GPU acceleration enabled
• Fixed: cropping circle of the lens profile for the Samsung Gear 360 (2016 model) was slighly too large
• If an unsuitable color profile was selected for the output (for example a source-only profile), PTGui would show a cryptic error message ('cmsCreateTransformTHR failed'). Now PTGui will show a more helpful error message.
• Fixed: Mi Sphere camera: automatic leveling worked only for JPEG images, not for DNG images
• Fixed: The PTGui web viewer (Tools – Publish to Website) only supported positive values, for camera rotation from left to right. Now negative values ​​can be used to get the opposite rotation.
• The Flash panorama viewer is obsolete and has been removed from Publish to Website.
