So, the inept person at saneal camera opened my canister of kodak hie film. I can't believe that.. I'm hoping my film isn't ruined. anyways. I was wondering if you had any tips for developing infrared. should I keep the dev tank in a light proof bag? or is it ok just shut? I also have ilfosol and was wondering what dev time at 20' i would need. the massive dev chart and the film box doesn't have it. i'm giong to look some more, but recently no luck.
