now that im done with college and have a real job, i can afford film and chems and i've been getting into doing B&W IR film. (Im gonna try some color but its 26 bucks a roll!!!)
Anyway The IR ive done in the past...all 2 rolls... I've shot at 320ISO and developed it for around 8 min (At Terri's suggestion) with really good results.
From what i have learned IR film is very touch and go and The Box tells me to shoot at 50-100 ISO and develope for 7.5 min.
I just got a ND8 Filter and im looking to do some long daytime exposures...(which has nothing to do with this months contest...)
So i was thinking, if its supposed to be shot at 50-100 and i can get great results at ISO 320, Im wondering if how slow can i make this film? 25? 12? 6? If i can pull it down that slow how should i change developement time.
Mind you that many places recomend a developement time of 5.5-10 min...(so its not all that precise)
Thanks for any help
