This past week I obtained a box of used film from a coworker for a song. He told me it had all been kept in cold storage until about a year ago when his wife wanted to reclaim freezer space. Among various kinds of 120 and 35mm film, there are 18+ rolls of expired Konica Infrared 120 film. I haven't checked them all, but it appears they expired about 20 years ago. My plan is to shoot a test roll using my Bronica SQ. I have a 25A red filter I'd like to use with it. (I know darker filters would be ideal, but that's what I have to work with.) I've found various suggestions for shooting and developing this film, but I thought I'd ask here in the hopes someone is familiar with this film. So my basic questions are: (1) Any suggestions on how to expose this expired film? (2) Any suggestions on developing it using D76? I can't really afford to buy some exotic developer to try, so I'd like to use what I have. Thanks!
