I recall having heard that the reason for this is that the emulsion's so sensitive it's subject to fogging by some flavor of cosmic particles (to which your freezer is transparent). And that Kodak stores unreleased batches way below ground, in a former salt mine (best not a Uranium mine, I guess!). I believe these things to be true, but they do have a certain `urban legend' quality of sounding like too good a story to be real. Anyone have hard references? I have noted that whenever I buy presumably new TMZ, the expiration date is much closer than that of other, slower B&W emulsions. -Jeff Moore <jbm@jbm.org>
