There are two camps to the expired-film-use brigade! A lot of the fascination comes from people who deliberately crave the various effects and therefore seek out the outrageously expired films - whereas many people here, myself included, use it because its cheaper and often the only way to come across stocks that are now consigned to history.
I'm able to fill my fridge with films I could never afford otherwise by slightly relaxing my standards on dates. Just last month - 600 feet of Ektachrome 100 Plus for AU$150, March 2007 expired and cold-stored the whole time.
I've been burnt a few times - the 1986 bulk of Ilford FP4 didn't really turn out too well, and there was the handful of 2001-expired rolls of Elitechrome 100 that must have gotten quite warm for some part of their lives - but as a whole I've fared pretty well. Got some
very nice results from 135 Plus-X expired in 1991, T-MAX 400 expired in 1998, Kodachrome 64
expired in May 1986, and even
this and
this from Ilford HP4 that expired in 1972 or thereabouts. I'm surprised at how well that's held up actually, although it is prone to emulsion lift. All the same, 100 sheets for free is nothing to scoff at
😛
Still got more Plus-X (this time from 2002), a handful of Ektar 25 in 120 from the early '90s, a spot of Panatomic-X from the mid-80s, one roll of Verichrome Pan from 1983, and my most cherished expired film - 35 sheets of 4x5 Tech Pan from 1994.
I did have a fair stock of early-2000s Fujicolor NPS as well, but I palmed that off to a lomographer because it does. not. like. being expired.
Now I just need a bigger fridge to put all of my stores of Eastman EXR film in. Gosh that 50D 5245 was a beautiful stock.
