Okay tommorow I'm gonna get an IR filter either at a store if they're not to overpriced or off the net. I've decided on the one that I want but I had a few questions for you smart folks I know it will work well on digital and then can be colorized in PS, but what if I were to use this IR filter on say TMax 100 or 400 speed film? Would it work successfully and would I have to do anything different in the darkroom to it? Also is it possible to use on color film and get decent results, say having that processed at walmart, would it work? Just curious...
