So we've had a couple of threads about Shanghai 120 film that suffered from the backing paper numbers imprinting themselves upon the film itself:

It came out completely fogged. I could barely discern some images on it, but my poor Epson V500 couldn't see anything
I have 3 more rolls from the same lot, so for the next roll I decided to give it my "desert stored" treatment: Shoot it 4x slower than box speed and
pull it about 1.5 stops in C41. I shot it in my WPC (pinhole) camera, so the ISO was very approximate at best, but after developing it for 2.5min in C41, I was able to pull some images off of it:
Backing paper numbers! But how did they get there? Then I remembered ... a couple of months ago, I had a film fridge accident (it tripped my circuit and warmed up overnight, and the stupid little freezer thing melted water all over my film). This particular batch were the only rolls that weren't in a box/canister/wrapper, so the film actually got wet. Since I let them dry with the backing paper still on, that must have somehow imprinted the numbers (and the black dye/goop?) onto the emulsions. Maybe the same thing happened with those unfortunate Shanghai rolls?
Anyways, a lesson is to be learned here: Keep your film dry!!
