I seem to have a bit of a problem with a roll of FP4+ that I (under)developed. I developed it in d-76H 1:1 with a little KBr thrown in. Well it seems I had a bit too much KBr b/c my developement time was way off by the looks of my negatives. They are extremely thin, underdeveloped, or whatever term you'd like to use. The negatives were properly exposed, but I'm not sure if that matters now that i've developed and fixed them. Anyway, I was going through 'The Darkroom Cookbook' and was thinking of using the Kodak In-5 Silver Intensifier formula. Does anyone have experience with this intensifier? Is there another one that I could use that will work just as well? The negatives are pretty faint, but I can see an image in each frame (35mm). Can I save this roll, or am I just s.o.l? Thanks!
