Title: Color Cast Removal
Post by: Mike Sellers on December 13, 2013, 01:13:32 pm

I have this old 4x5 transparency that has a strange color cast to the sky that I am trying to remove. It almost looks like a chemical problem from the developing process?

Looks very problematic to me, since it seems to be a non-uniform artifact, be it from development or from storage/aging/fungus.
You might check in b/w mode if it goes through to the luminance information of the image.
If not you might use some fake color to repair it, if yes the problem is even bigger.
