Kodak High Speed Infrared 2481 Exp 05/88 35mm
I don't know if I was given good info or bad, but I was told to keep HIE in the fridge and not the freezer. No idea why. I've also heard that it's not great much beyond its expiration date. I've shot some that was a year or so past the date and it was ok, but grainier. I have one roll left (exp 10-09) and I'll be shooting it soon. Its responses have nothing to do with heat, btw, it just registers colors in different shades of grey than regular B&W film. But still pretty cool. It has to be taken out of the can in total darkness, loaded into the camera in total darkness, unloaded, etc...., so it's best to be able to develop it yourself.
