When reading CR3 files (e.g. from Canon EOS M6 Mark II, all the R-series cameras) the exif data is unavailable. When I use the official AppImage of RawTherapee or the Archlinux package of RawTerapee, the exif data (like the used camera, lens, focal length, etc.) is available. Lack of exif data is very inconvenient as it prevents use geometry or chromatic aberration correction. Reproducible: Always Steps to Reproduce: 1. Start rawhterapee 2. Navigate to a .CR3 file 3. Open it in main window, the application shows "Exif data not available." (in case it doesn't, pressing "I" on keyboard should show that in the overlay on the photo in the top right corner Actual Results: "Exif data not available." Expected Results: Picture metadata available: camera make and model, used lens, photo parameters, etc. IIRC the issue may be related to the libraries used by rawtherapee
Maybe some library update have broken RT. I'll see if a rebuild fixes this. BTW, I've just noticed RT in F40 is totally broken too :(
From exiv2 release notes it seems that CR3 files uses bmff format: > Highlights of Exiv2 v0.27.4 > > Support for bmff files (HEIC, HEIF, AVIF, CR3, JXL/bmff) My guess is that Fedora provided exiv2 doesn't support those files: https://bugzilla.redhat.com/show_bug.cgi?id=1979565
FEDORA-2024-0ac26cc89a (calligra-3.2.1-31.fc41, darktable-4.8.0-3.fc41, and 38 more) has been submitted as an update to Fedora 41. https://bodhi.fedoraproject.org/updates/FEDORA-2024-0ac26cc89a
Note that this can only be fixed in Rawhide (F41) because it needs a newer exiv2 which breaks backward compatibility.
