Re Gene's experience with IR film, I have had mixed experience. I have a few rolls of 35mm Kodak IR film in the freezer which is five years out of date and (as of three months ago) had no fog problems. OTOH, a few sheets of 4x5 IR film I shot this summer which was two years out of date (and had been frozen the whole time) was so fogged as to be worthless.(posted 8726 days ago)
