Jerry and Ron,
I shot a new roll last night, and it's in a metal can to age a little.
Assuming I have 38 black plastic/metal film cans (from Fuji etc.), and if I can figure out how to reliably measure and cut the frames in the dark, I'll cut 'em up and freeze them.
Thanks for the idea.
BTW, do you know if the latent image can decay rapidly at some point in time? My images were consistent until the two-day heat-wave, and then they nose-dived. It's as if some threshold was crossed causing rapid decay.
