Thanks, all. Anyone got any links for tips for developing C-41 B&W? I know it's going to be a little odd because of the backing color, and I'll likely switch to something clear, but I'm using up some old film.
No, I have 6 or so rolls of BW400CN, and they haven't been stored the best, so I figure it's worth experimenting with. Then once I get some fresh stuff, I can do the developing a little more confidently.
