For several weeks now I have been getting very small, dark spots on my tri-x negatives. They are not dusts specks, as I cannot clean them off with film cleaner. They are part of the negative. I'm talking about a LOT of spots...sometimes 30 or more per frame.(posted 8519 days ago)What is strange is that the spots are showing up very prevalently at the beginning of a roll, and few if any show up on the end of the roll. I develop in stainless steel tanks, and the beginning of the roll is what is at the inside of the reel, so I'm thinking there might be some kind of connection. At first I thought they might be tiny air bubbles, but shouldn't air bubbles make transparent spots rather than dark ones?
Here's the other info you might need...tri-x diluted 1:1 at 68 degrees. I agitate for 10 sec every minute. I use kodak hardening fixer and a hypo clear, followed by a very dilute photo-flo bath.
