A Low-Cost Option…
Buying expired film at a bargain price might seem like a good idea. Some (not me) even claim that, like fine wine, it improves with age.
I should note that my opinion is based on black-and-white film.
…But Not Without Risk
Expired film can deteriorate quickly
Ideally, the seller has already tested the expired film or received feedback about it and can confirm that it’s still usable.
Keep in mind that expired film can degrade very fast, and yesterday’s truth may not hold today.
A little moisture or heat, and suddenly your images become unusable.
Exercise Caution
If possible, test one roll before buying the whole batch. It would be foolish to pay for film that ends up in the trash.
Don’t hesitate to ask how and where the film was stored. If it hasn’t been kept in a fridge at some point, its condition becomes questionable.
Wasting Time and Headaches
Finding the right sensitivity
Expired film doesn’t behave the same as fresh film. Over time, its sensitivity decreases.
For example, Kodak Verichrome marked 125 ISO and expired in 1974 required exposure at 25 ISO, or even 12 ISO, to get usable negatives. This takes testing and consumes time.
Using stand-development is a simple solution to avoid overthinking development times.
The Emulsion “Self-Develops” Over Time
More problematic, old film can develop by itself, turning gray where it should remain transparent. This also happened with the Verichrome I tested.
For 120-format film covered with protective paper, the ink or texture of the paper can imprint onto the emulsion, ruining your images.
Numbers or marks floating in the sky will spoil your shots.
I encountered this with 120 format HP5+. There were also traces of “lime deposits” inside the packaging.
Conclusion
For me, it’s not worth the gamble.
If you want to do serious analog photography, you shouldn’t rely on luck, you need consistent, predictable results.
The highly variable (and sometimes completely unusable) results of expired film simply aren’t compatible with that.
