Not sure whether this is the right place to address this problem; if not please advise.
When I got my Canon R5 in June of last year, .CR3 Files could not easily be processed in Darktable 3.6. Adobe’s old DNG-Converter produced DNGs that Darktable did read, but they looked horrible. However, DxO’s Pure Raw resulted in very nice looking DNGs. Since version 3.8, Darktable was then easily able to process .CR3 files, but usually the DxO results are cleaner (no wonder, for the price), although sometimes a bit oversharpened.
I’m currently using Aurelien Pierre’s R&Darktable and ran into the following problem:
Having two versions of the same file, .CR3 and .DNG, processed to look roughly similar, I tried to export both to a JPEG. But while the JPEG originating from the .CR3 file looks fine, the one from the DNG is way too dark. The same problem occurs when exporting PNGs.
