is 5 years old

I found a box of hp5+ sheet film that I bought in 2000 or so, and has
been laying around upstairs, partially used, since 2001. It was dated
2005, but has been sitting in a room that gets pretty warm sometimes in
summer (certainly up to 80F). Am I correct that its probably pretty
close to just fine though?

Its probably OK provided no moisture got into it. I
recently used some HP-5 in 120 roll size that was about 12
years old and got perfectly good negatives. Of course test a
sheet before using it for anything important.
Moisture can cause an odd mottled fog and is not
responsive to bromide.
I've used film that was nearly 20 years old with good
results. Very old film will become somewhat fogged. If only
slightly fogged you need only to increase exposure a little.
If you want to eliminate the fog add a little Potassium
bromide to the developer. For D-76 around 0.25 to 0.5 gram
per liter of full strength developer is enough.

Is there any advantage in freezing black & white film for storage, or
does that really only apply to colour film?

I know I always freeze it if it osnt going to get used for a few years,
or if the expiration date approaches. Cant hurt anyway.

Also applies to B&W. Freezing slows down the chemical
reactions that continue in the emulsion and result in fog
and other changes. It also works for paper. Freezing is now
recommended for archival storage of processed photographic
materials for the same reason.

From what I understand, if you are going to freeze photographic
materials which have been removed from their original packaging,
it is a good idea to seal them in an airtight container with
some desiccant.

I also understand that film (especially fast film) will
eventually fog from background radiation. I haven't seen
any real data on this, but I have the impression that
hp5 will show significant fog after a decade or so.
I have some hp5 which expired in 1982 left over from
into photography as a kid which was stored in a reasonably
cool and dry place. I used a bit of it a few years ago
when I got back into photography and it was certainly
usable in the sense that one could take pictures with
it, but the fog level was rather high.

I bought some old Leica cartridges on Ebay a couple
years ago and a few of them were loaded with film.
The film turned out to be Agfa Superpan on nitrate
stock with BH perfs. The film must be something
like 70 years old, but the fog didn't seem any
worse than the 25 year old HP5 (it is hard to tell
because 35mm HP5 has a grey base and the old nitrate
film looked brownish and I'm not entirely sure how
fast Superpan was though I'd guess ISO 50). I think
I still have three rolls.

Thanks - so it's into the freezer with all the AXP and Scala I can get
my hands on.
