    Expiration Tolerance of HP5+ Sheet Film?

    I just picked up 3x boxes of 4x5 HP5+ sheet film (75pcs) for a good price. It was a good price because it expired in May '07. Yes, it has been kept refridgerated and yes I'll be tossing it in the freezer when it arrives. With 35mm and 120 b&w films I've never really had an issue with expiration dates prior to exposure (post-exposure is a different story). In fact, the PanF in my 6x12 filmback expired in April of last year

    Here's the question: due to the difference in thickness between sheet film and roll film due I need to be more wary here? I mean, with development there are sometimes differences because of the thickness.

    Thanks!

    Hi Brian,
    I have been using 4x5 HP5 that expired about 8-10 years ago.
    Looks as good as the current stuff. No problems at all. The base fog is small.
    You should have no problems with your 07 batch.

    Best

    Should be fine. I doubt any deterioration has started, given the cold storage.
