My father in law found a duffel bag of old film cameras asking me to sell them. Well they weren’t worth anything, but many of them had partially exposed rolls in them.
I developed the only 35mm roll with a 1 stop push and it was completely black (fogged). I asked him where they were stored and he said the duffel bag was in his attic so I figured the rest of the rolls were complete toast too.
Anyway, I mixed up another batch of c-41 but this time added 5ml of AF-2000 (an anti foggant). These were 110 film (tiny) and I don’t have any reels that would fit. So I just developed in a bucket. I heated the developer to 39º C and developed for only 3:15 (to prevent more fogging) moving the film around by hand. Then rinsed, turned the light on and did the same for bleach and fix. They actually turned out!
The best of which are pictures of my wife as a baby! The film has been sitting in these cameras for 40 years in the attic. The first image is actually my wife's mom and was taken in the 70's. So 50 years old! The backing paper of the 110 / 126 film seemed to have helped preserve it.
