Hi,
unfortunately it is not that easy, because not only have you to
invert the colors, but to "subtract" the brown color from the film
strip also. I'm not sure, but my first guess would be that this is
not easily done in GIMP.

Remember: There are only two tools in life. WD-40, for when something
doesn't move, and should, and Duct Tape, for when something is moving
and it shouldn't.
So does the universe explode if you spray duct tape with WD-40?
