Compensate expired B&W film


I do have an unused Agfaphoto APX-100 136 B&W film that is 5.5 years expired by now.
Despite this, i would like to use it (on a Pentax analoge camera i guess) (and develop it myself).
Can i compensate for it's age by modifying exposure setting/developing time, so to get good results nevertheless?
When your answer is 'yes', i would be grateful for suggestions (best from some who had the same issue before).

Thank you,

Medium speed B&W films should keep very well, especially if properly stored (not too hot). I would give it just slightly more light, like +1/2EV, than fresh film and develop normally. Stored too long/too hot, B&W film gets 'fogged' over time and higher speed film loses sensitivity. Increasing exposure helps to work around both effects, but may of course make highlights a bit dull.

I recently developed some APX100 which expired in 2003 and was stored at room temperature. Developed normally, there was a slight fogging and in the very bright parts of the negative, the numbering from the backing paper (120 format roll film) is visible.

If you have more than one roll, use the first roll to test for necessary compensation. There are is no rule of thumb for compensation and the amount of surprise can be reduced by testing first.

If you only have one roll, shoot a couple of exposures and cut then develop. I have used a changing bag, but going into the darkroom is much better.

Shoot a gray scale, develop normally, and judge from the negative for development changes needed if any. Old film can pick up some fog but that's unusual for 100 speed so I would guess if it has been stored well, it will work fine.

I too have some of the last Agfa Gevaert 35mm APX100.
Mine has always been stored cool or cold but not frozen.
With normal development the negatives come out fine.
