Thanks Pascal, but i had already tried that. Even though the image has pure
(clipped) white in it, what the invert plugin results in is a badly clipped
purple image. That's why i said the plugin was showing weird behaviour.
I've also tried selecting the actual film color and also black and a
mid-grey, nothing seems to get me usable results. I think there is a bug
with the plugin. Or does it malfunction only on my computer (because of a
library issue maybe)?
Here's a RAW file of a negative "scan", you can try it yourself:
