regarding light piping.....

when i got my 100 foot roll, i loaded 6 rolls. the first 4 were shot within a week of loading them and they came out great. the other two sat in white film cans. about 2-3 months later i shot the other two rolls. the first 6 frames on those rolls had a terrible yellow cast, then next 3 a light yellow cast and the rest where fine. so if you do load them use them ASAP.
