Hi,
A friend who went to the dark side (digital) gave me some expired Agfa APX film which has been stored at room temp for the last 5-6 years. I have a roll of APX 24, a couple 100 and 400. So are these still good? Should I process normally? Thoughts?
Unless room temperature means uncontrolled and they went up to really high temps (e.g., during the summer of '05, etc.) for an extended period, I would think you would be fine.
BTW, I assume you mean APX 25, not 24. But if the latter, a wee bit finer grain will be da bomb!
I'm down to my last 50 sheets of APX 100. It's 5 or six yers old and still working fine with no changes. I keep mine at 40°F, though. The film should be OK. Especially the 25 and 100. The 400 - I would bracket my shots to hedge my bets.
If the film has fogged, the only problem you will run into is more grain. Because fog can be treated as film base, where you expose over that amount. Say Agfa 100 tests out typically to ISO 50. This would mean that to get the density of Zone I over the increased fog, you lower your ISO speed to say 40, or 32. Your development time will increase a bit since the fog has decreased the contrast. The increase in overall density and development is what gives you more grain. You could always print through fog, unless it's dichoric fog, or uneven streaks.
I just a month ago shot apx25 120 that I bought years out of date, with unknown storage conditions. The slower the film, the more stable.
I still have a dozen or so rolls of some GAF (rebadged Ferrania I think) 25asa in 120 from the 60s, but long term chilled or frozen. It is down to about 16asa, and a bit low in contrast, so I just rate accordingly, and moderately overdevelop when I use it.
