What was being used in the 1970's with photographs that caused them to fade to red? Pretty much every picture that I've come across that was dated in the 70's has a red tint to them. I'm just curious what caused this. I haven't really noticed it in any pictures from any other decade.
Was it something in the emulsion solution where the other colors were just weaker, and so over time they would fade but the red would remain, or something else?
