I have a 15-stop ND filter that causes severe vignetting, even at f/22, even though I don't see any vignetting without the filter. A quick solution is to use the vignetting tool in Capture One and brighten the edges. While this works, I can still see some nonuniformity. So I was thinking of taking a calibration image of a uniformly illuminated area using the filter, and use that calibration image (or its inverse) as a mask to brighten the actual image. I have used this method in my astrophotography work. However, I cannot seem to find a way to do this in Capture One. I would have to import the calibration image as a mask/layer, but Capture One only allows me to use brushes in mask/layer. Is there a way to do what I want to do, or am I stuck with the vignetting tool?

Sorry in advance for not addressing your question, but is there something you do not like about C1, or are you just trying to see what else is out there before committing? If you don't like to price point, do you by any chance have a Sony or a Fujifilm camera? C1 offers discounted versions that work for just those cameras (if you buy the Sony version, you can only import Sony raws).
