20 year old AgfaPan APX25

[Danner]

Found a roll of 135-36 APX25 in the back of the 'fridge, about 20 years old. Looking for guidance on exposure and processing. My initial thought is to shoot it at ISO 12 and develop ISO 25 according to the MassiveDevChart (probably in 1:1 XTOL?. Does that sound about right?

Thank you for your thoughts an suggestions.

It's probably just fine. APX25 lasts really well when in the fridge. I'd shoot it at box speed and develop normally.

20 years old and refrigerated: it should be fine. B&W film is amazingly durable. Here are some examples of even older Panatomic-X:

I still have quite a few 120 rolls. I shoot it as if it were fresh and have had no issues.

Thanks for the replies, I'll shoot it at box speed. I looked on Ebay, and there were some 10-roll bricks available for about US$100, which isn't too bad. If the roll I have provides good results, I may get some more. Hoping for some really fine grain and high acuity.

Be sure to ask the sellers about the film's storage conditions. Cool plays a major roll in reducing chemical reactions and deterioration.

Any slow B+W film (under 100ASA) keeps forever-- 40 years expired and it's almost always within a stop in my experience; 50-60 years add 2 stops at exposure, develop normally. Once you get to 'fast' films- 400ASA/ EI/ ISO whatever- it's more difficult to get a true rule of thumb, and everything is on a case by case basis. I am lucky to live in SoCal where we get so much sun I can experiment with some really old stuff.
