SUMMARY The white balance for CR3 images converted using the linux digikam 7.1.0 is corrupted, and image metadata (lens,aperture,ISO,exposure, focal length, etc) is absent. Images are strongly magenta. Other software (such as darktable) produces a warning ("failed to read camera white balance information"). Images converted through Adobe Digital Negative Converter 12.4.0.555 on Wine work as expected. STEPS TO REPRODUCE 1. Set the checkbox "convert DGN" 2. Import the images OBSERVED RESULT CR3 files converted to DGN format have corrupted white balance information. The JPG preview has a bad white balance. The image metadate is lacking all camera metadata (lens, aperture, exposure, ISO, etc) EXPECTED RESULT The resultant DGN format image should have white balance information that reflects the image. The white balance and metadata should be able to be read by other image manipulation programs capable of reading DGN files. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Kubuntu 20.04 (available in About System) KDE Plasma Version: 5.18.5 KDE Frameworks Version: 5.68.0 Qt Version: 5.12.8 ADDITIONAL INFORMATION Running Digikam 7.1.0 I have sample images, but as these are raw and DGN image produced by the Canon R5, these images are 41-45MB in size. How can I submit these?
The reasons are simple : 1/ Exiv2 shared library do not support yet CR3 file format. There is an upstream bug open here: https://github.com/Exiv2/exiv2/issues/236 2/ Libraw shared library do not support yet last Canon camera models with CR3 files (as EOS-R5). Check well the camera models listed in Help/Raw Camera Support dialog. Look also this other report: https://bugs.kde.org/show_bug.cgi?id=426923#c9 Gilles Caulier
After upgrading DNG SDK to 1.5, libraw to snapshot 20210504, digiKAm 7.3.0 using Exiv2 0.27.4 can handle Canon R5 and convert to DNG without problem. Screenshot : https://i.imgur.com/JOUYv6q.png I close this file now. Gilles Caulier
