DrDre, I don’t think I’ve read you mentioning it… have you heard of the Digital ROC color-restoration processing plug-in by Kodak subsidiary Applied Science Fiction?
I don’t know that the product has been updated for many years. My Nikon film scanner came bundled with a version, but it only works during the scanning of film. Worked fairly well. Reminds me of your work on restoring color to red-faded motion picture film scans.
ah damn, they just discontinued them and no longer allow downloads after June 2019! just missed this, darn
