I don’t know if this is the right place to mention bugs for Dev appimage versions of RawTherapee, but there are a couple I’ve noticed when working with digitized colour negatives.
- The spot white balance tool doesn’t work properly. After using the Film Negative module so the image is now positive, clicking with the spot white balance tool puts a strong orange mask over the image. It’s still a positive image, but with an orange mask. On the other hand the “pick white balance spot” in the film negative module works properly. It should be noted that in ART, the spot white balance works properly.
- Again, working with colour negatives, the white balance temperature slider works backwards in RT dev version, but normally in ART.
