Remove vignette doesn't work for certain images?

[NablaDelta]

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!

There's no lens info in the metadata so Photo doesn't know what to do
You could try
exiftool -Tagsfromfile goodfile test.tif
to see if that helps. By goodfile I mean the original capture so that the metadata is intact
Or you could experiment with
exiftool -Tagsfromfile Panic.mie test.tif
which will embed metadata for an Olympus ED 12mm F2.0 lens and reduce the vignetting but the distortion correction may not be acceptable
Panic.mie was produced by
exiftool -Tagsfromfile P9170025.ORF -lens* -make* Panic.mie

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!
