I bought a box of expired film recently. In it were approx. 200 rolls of 35mm film that included 40 rolls of Tri-x from 1984ish (lots of fog), 40 rolls of Ektachrome from 1984ish and 40 rolls of HP5 from the 90s. And a whole bunch of consumer kodak and fuji films. But there were some really awesome films too that I will keep and use. Those were original Ektar, all sorts of Ektapress, some high speed konica stuff and some panatomic-x.
I would use it all, but I don't like surprises. I've been giving it away to other photogs, and they've been pretty happy about it. What would you do with a huge box wildcards?
