Thanks for that further information.

Professional film is generally stated to be intended for prompt processing after exposure, whereas consumer film should keep much better, to allow for typical amateur/family use.

I tend to use Pro film in circumstances where I need the photos quickly anyway, whereas I'm quite happy to leave a consumer film in a camera for several weeks. I've a C-41 Fuji film that's been in a old Zorki camera, which I'm trying out, for probably three or four months, and I'm not expecting any deterioration for practical purposes. However, I'd probably not want to keep an exposed Pro film for more than a week or two before processing.

Maybe PE could comment on whether freezing does affect the latent image on a typical film?
