Tri-X 400 expired 1993 - Which ISO?
Hello, Guys. I recently was presented with 40 Tri-X 400 35mm expired in 1993. I don´t have much info regarding how they were stored, but I´m almost sure they were not kept frozen. I guess they were stored on a shelf in a garage where room temperature ranged from 5° at winter to 35° at summer. They are in their original packing wrapped in plastic in bricks of twenty.
My question is: which ISO should I use? I tried some at 400 ISO and images were so faint that barely could be seen.
Thanks in advance for the help.
