I think the longest period of time I have left film undeveloped was just
about 15 years, unintentionally I should add, and it did process quite well.
I added to the development time, giving it about 1.5x normal. This was
guesswork, but has worked pretty well on several occasions.

Subject: 15 year's old, unprocessed
Forgive my off-topic (?) posting.
I joined this list b/c from the name I thought that it might help me with my
problem, but now, after reading a few posts I see that perhaps this isn't
the place. But I was still hoping that someone could steer me to a list or a
resource that might would some answers to this problem:
I have some b & w film that was shot about 15 years ago but was never
processed. It's mostly Plus-X shot at 250 although there is some shot Plus-X
at other speeds. And there is a little Tri-X shot at speeds as high as 1600
or 3200 as well as some TMAX shot at 400.
All this film was refrigerated for the majority of that 15 years. But not
for all of it. :(
My concern is that I understand that quite aside from normal film chemical
degradation, that an unprocessed latent image will begin to disappear from
the film as time passes. Is this true? What is the best approach to salvage
this film? Should it be processed differently than if it was freshly shot?
If so how? Who would know about this strange problem?
Thanks in advance,
