In that case it should relatively easy to add that It could be, yes, but I do not think a pure math way is the right way, images are "more white, no, less, tweak that". > functionality to some of the file plug-ins.

I think it should be visual, a window with the image in 8 bit, and controls that decide how to get that 8 bit from the original 16 or 32. Basically black & white points and a curve. I say visual, cos it could mean what one does in the lab, but digital (load some copies, adjust each one at will, and mask and mix all the copies to get the final image). PNG should be included in this family too, BTW. Any other format? GSR
