Thanks to another APUG member, I've come into the possession of a 100ftx70mm roll of Aerochrome infrared, which I plan on cutting into single sheets and shooting in cut film holders. While 100ft will give me a little over 350 exposures, I want to keep the experimentation to an absolute minimum. I've been reading up on false color infrared film for the last week or so, so I'm not totally ignorant. I already have a wratten #12 (minus blue) filter, though I've read that using orange or red filters will give interesting results, too. In terms of processing, I've read arguments for and against both e-6 and c41. Some said to *only* develop aerochrome with the proper AR-5 process, but it's unlikely that I'll be able to do that. I already have some C-41 chemicals, so that would be the easiest route. If I developed in C-41, would I be able to print with RA-4? I was originally planning on getting ahold of the E-6 chemistry and printing with the RA-4 reversal method as described here, but, if I remember correctly, PE said something about EIR in c41 creating a really interesting effect. C41 and normal RA-4 would certainly simplify things for me. What would the benefits be of using E-6 and printing with something like ilfochrome (which I've read is very expensive...)? The documentation for EIR says to meter at ASA 200 for E-6; what should I set my meter to for C-41? Do I meter through the filter or without it? Also, my biggest concern is accidentally fogging the roll while loading it into holders. The can is sealed and frozen, so nothing could have happened yet. Should I take any extra precautions in terms of handling it than normal color film?
