Old film. During a clearout today I happened across some old expired 35mm film. Provia 100F - Expired 2008 AGFA HDC Plus 400 - no date but from same era Ilford PanF 50 - no date but from same era And an exposed Ilford Delta 400 - ditto The PanF has been sat on a shelf out of its box. The rest have been in the dark inside their canisters. Would you bother using them? If so do I need to do anything like adjust the ASA on camera? Is it worth having the Delta 400 processed?
