Thanks for your help! I didn't know remove vignette was reading the metadata but thought it would use some simple function that would work for most lenses. Copying the metadata using the exiftool command worked well for both an own raw image and your panic file. However, unfortunately, it doesn't help for the vignette tool, probably since the pixel dimensions don't match the expected aspect ratio. Anyway I understood why AP is behaving as it does (although I would prefer some kind of warning), and the more sophisticated vignette tool next to "remove vignette" also does the job. Thanks again!

If I try Filters > Colors > Remove Vignette on the attached TIF nothing happens. For other images I am able to remove the vignette, but on some files it just doesn't work. It might relate to the color and/or the bit-depth, but I cannot clearly figure it out. I hope you can help, thanks in advance! test.tif
