Een regelmatig besproken stukje software in het Foto & Video Workflow-subforum is PTGui. Dit programma richt zich op het maken en aanpassen van samengestelde beelden. Dat kan een verticaal of horizontaal panorama zijn, maar ook één groot beeld met een enorme resolutie dat samengesteld is uit talloze afzonderlijke opnames. Met een stapel foto's als invoer kan het programma daarna zelf uitzoeken hoe ze naast elkaar gezet moeten worden. Voor het rekenintensieve deel kan bovendien via OpenCL de gpu worden ingezet om sneller klaar te zijn. De software is beschikbaar is een standaard- en pro-versie; de verschillen tussen beide worden op deze pagina tegen elkaar afgezet. Kort geleden is versie 13.2 uitgekomen en hierin zijn de volgende veranderingen en verbeteringen aangebracht:
Changes in version 13.2:
- Improved highlight recovery for RAW/DNG source images. If a negative exposure offset is applied to the panorama, or if tone mapping is used, PTGui is able to recover some more highlight detail from the source images. Previously this would have been clipped to white.
- Images from the DJI Mavic 4 Pro are now automatically positioned upon loading, based on the metadata embedded by the drone.
- Added support for the Insta360 X5 camera. Note that automatic levelling is not supported for the X3, X4 and X5 cameras, because the cameras do not appear to provide the necessary metadata.
- Because images from DJI drones are positioned automatically upon loading, the flag "Images are already roughly positioned - only search for control points in overlapping areas." is now automatically set. This will speed up the alignment process, especially for large panoramas taken with the Mavic 4 Pro's tele lenses.
- Updated LibRaw to the latest version. No new cameras were added but this may fix some problems when handling certain raw files.
- The location of the licensekey.json file can now be specified using the environment variable PTGUI_GLOBAL_CONFIG_DIR. This should point to a directory containing the file licensekey.json. If the environment variable is not set, or if it points to a nonexisting directory, PTGui will look for licensekey.json in C:\ProgramData\PTGui\ (Windows), /etc/PTGui/ (Linux) or /Users/Shared/Application Support/PTGui/ (macOS) as before. See Q2.13 on the Support page for more information.
- Windows: It's now possible to rename and delete TIFF files while PTGui is still busy loading them. Previously the files would be locked and Windows would refuse to rename or delete the file until PTGui finished loading the image. This can be useful when editing source images in an external editor. On Linux and macOS this was already possible.
- Fixed a bug which could cause PTGui to crash if the the disk for temporary files became full.
- Fixed: the patch editor failed to save (with an Assertion Failed error) when opening certain images from outside PTGui, lacking EXIF data.
- Fixed: images taken with DJI drones in portrait mode would be incorrectly rotated because PTGui would place them at a roll angle of 90, while the image itself was already rotated 90 degrees.
- Fixed: on computers with both an integrated Intel GPU and a dedicated (nvidia or AMD) GPU, PTGui would sometimes prefer the integrated GPU for stitching, which is usually much slower than the dedicated GPU. PTGui will now use the dedicated GPU when the device is set to Automatic.
- Fixed: The white balance (temperature / tint) was reported incorrectly for certain images developed with Adobe Camera Raw
