In the early 1970s I shot and home processed a lot of GAF film, mostly GAF 64. As I recall the GAF process was similar to Ektachrome Process E3. As I remember it required a light, not a chemical, re-exposure step. I do not remember what the GAF process was called. GAF 64 film was cheap and lovely and came out great when you developed it yourself. The problem was GAF's own processing was terrible and the film got a bad reputation and was discontinued. I developed my own Ektachrome (E3 and E4) and GAF at this time in my life.
GAF is General Aniline & Film or GAF for short...
Does anybody recall what the GAF reversal process was called?
