True. TMZ's high speed also makes it vulnerable to fogging over time from
x-rays, gamma rays, and sting rays for all I know. Freezing it won't help,
nor will keeping it in one of those Film Shield lead bags -- a lot of
radiation goes right through them (they're specifically designed to filter
airport-level X-rays only). I've heard that Kodak stores its inventory in a
deep salt mine, which does cut down on a lot of the background radiation. I
try not to buy more than I'm going to shoot over the next month or two, and
pay attention to the "use by" date. Unlike Kodachrome, I don't buy TMZ if
it's close to or past the expiration date on the packaging.
