Answer to double correction possibility...

Already got a dumb question : what happens if you "Correct" an already corrected file?

The obvious answer must be "nothing, black pixels are now neutral", but I had to ask!

Actually, that's a good question and one that I've already taken care of. First, double correction should be impossible as I check for file names starting with "mc_" for the source files and also that the equivalent name starting with "mc_" in the destination folder does not exist before proceeding with correction for each file. Second, as you say, on the off chance that the user renamed a corrected file to remove the "mc_", the correction should do nothing as the masked black areas with be corrected to appear as expected "normal' by the correction algorithm; thus, the correction should end up to be zero. I will check this, however.
