Thanks for the comparison; the untouched frame doesn’t look too badly faded at all. Is this Fuji type of print therefore generally more stable and slower to fade to red than whatever was used for the Grindhouse print (Eastman?).
From what I understand (and feel free to correct me if I’m wrong), Eastman film was by far the worst when it came to fading because their cyan dye was basically trash. Fuji has other drawbacks that Kodak doesn’t, but as far as fading goes, it supposedly lasts about twice as long.
