A Wired Article points out that Tri-X is 61 years old this year.
I was a little slow on the uptake of Tri-X. My very first experience with black and white film in High School was with the brand new (then) Tmax. I distinctly remember my Photography Club proctor saying “I hope this works with regular developer because we don’t have any Tmax developer.” It did. Almost a decade later when I picked up photography again in 2001 Tmax was about all the local Ritz had.
