I was under the impression that lith film had a fairly short shelf life. But today I pulled out a box of Kodak Ortho Lith Film, Type 3, with an expiration date of 1986. I was about to discard it but decided to test it on the off chance that it might be useful for something. I was very surprised to find that the tests looks very good, with no general fog and good Dmax. And to the best of this knowledge this stuff had been stored at room temperature, not frozen. Is this typical of lith films?
