What happens when film is expired?

Over time the chemicals on the film lose their potency and start to deteriorate. The silver halides in the films’ emulsion degrade and lose their sensitivity. As a result, colours will lose their vibrancy, and contrasts will fade and grain increases. Eventually, expired film becomes foggy and unusable.

How long can a film stay in camera?

It depends on the film, but in most cases, years. The big exception is Ilford Pan F, which has big problems with latent image retention. Ilford recommends processing within three months of the first shot, others say you shouldn’t wait more than two weeks.
