So I bought a darkroom off a guy who's dad was a professional photographer. They closed the studio last year and this stuff has been sitting in his garage for a year, I'm going to guess the summer heat killed this stuff. The Ektachrome dates back to '79, the other films range until early 90s. Such a shame most of them are unrolled 100'. I'm probably going to test some and develop at home, any tips on trying to recover expired film? Or is it not even worth doing, he basically gave this stuff to me with the other things I bought.
