I have been keeping an eye out for expired 16mm stocks so I can practice shooting film, getting my head around things, experimenting etc. I have been focusing on B&W stocks as I am of the belief that less sensitivity is still workable, whereas with expired colour stocks I figure the dyes must degrade in a haphazard way, like having a red or blue streak running through the film.
Of course these are uneducated assumptions, is there a web site that details how stocks degrade? I imagine a few people rely on expired stocks to actively remain shooting, and knowing how some stocks will degrade will help purchasing decisions of auction sites.
Any ideas on where this info is?
