I developed a few rolls of ~20 year old film a while back. I only tried
Rodinal and D-76. Hands down, Rodinal produced much less fog. The old
rolls of Plus-X, developed in Rodinal at standard times plus 10%, looked
as good as new. Tri-X showed some fog. I had one roll of HIE and it it
degraded significantly - no IR effect, very compressed tonal range, very
foggy.
I did not use HC-110 and have since read that it is a good choice for
developing old film.
Note that the film I developed was merely 20 years old. I did not
develop a 20 year old latent image.
A quick google of "developing old exposed film" produced this:

Good Luck!

Hi All,
I discovered a few rolls of undeveloped B&W film that are 20-some years
old that I shot in late 1980s.
I don't expect anything extremely valuable, but some shots might have
some sentimental value.
I wonder what would be the best way of trying to develop them.
(I don't have any equipment for many years).
1. These rolls are Russian-made Tasma and/or Svema. Does anybody
know by any chance (I didn't google this question in detail yet)
if the process would be much different from that used for B&W film
in the US/the rest of the world, and what is the correct name for that
process (like C-41, ...).
I found mentioning about the processing was similar to
"..Agfa 12, but any other developer (D-76, Microphren, etc.) will do".
I don't know if this is correct, but assuming this is, - maybe that
would help in the next question:
2. Is there any lab that still develops B&W film and does that by mail
(in the US)?
3. For these Russian films, the processing time was not
standartized, and was specified on the individual boxes.
If I were to find a place that would agree to develop these films,
would they agree to use the timing I request?
4. Any other suggestions of how to proceed?
5. Is there anybody on the list who still does wet-processing him/herselve
and has everything handy and running (within US and maybe Canada)?
If so, would you agree to develop these films for me (there are only 3-4 rolls)?
I would be happy to compensate for the nominal expenses and mailing them.
Thank you for any and all helpful references and information!
Igor
