UNDEVELOPED 35mm B&W FILM 30 YRS. OLD, STUCK TOGETHER. HOW TO PROCESS

[HOLLY MAXSON]

I have 35mm b&w film which is stuck together due to humidity/mold. Any suggestions on processing?

I'd gently soak it in water until it became unstuck, then develop one sheet at about N+2 (to make up for lost speed & contrast) and see how it looks, then adjust the rest accordingly.

Good luck!

Oh, sorry - just realized you have 35mm film. Same basic process - soak the film in room temp. water for a while then try to gently unwind the coil of stuck film a bit at a time until you can load it onto a reel (you're going to be in the dark for a while - bring a radio!). Then develop it about 50% longer than you'd develop the same film if it were fresh.

Luck,

Also, add some Benzotriazole to cut down on the fogging you'll get from the age of the film.
