Am excited about learning/discovering new things about paper negative's. I've already mentioned the two open packs of old outdated paper that I'm working my way through. It seems one pack may be a lot older than the other(like it was with Columbus when he discovered America). The early trials were made using the pack with the least amount of paper and worked well as about 3 ISO for portraits and developed in old dilute Dektol. However trying the pack with the most paper didn't work out as well (the Columbus pack),after several attempts and increasing the exposure drastically the resulting negatives were thin and had a heavy uneven base fog. Have decided that pack's not good for portraits but may give it a whirl for landscapes without any flash exposure (hate to waste stuff ya know).The whole paper negative thing has revived my interest in photography and is great fun to boot.
Really appreciate all the information you all share openly here.
