Hi everyone. I recently found a 100 ft. bulk roll of Velvia 50 in 35mm format expired 1999 but refrigerated. If I do my math right, I should be able to get around 20 rolls of 36 exposure and 30(?) rolls of 24 exposure. So that's about $3.50 per roll. Is it worth taking the risk of expired film (again, refrigerated) and the hassle or dust, scratches, and maybe light leaks? Thanks.
