I feel like Tri-X like the guy in the book, "The Millionaire Next Door"; The only Tri-X I shoot is free Tri-X! I'm shooting some now only because a buddy couldn't use the 220 rolls some one gave him. The new Delta 400 is much better. I'm considering adding it to my two staples, TMX and Tech Pan in 120.(posted 8340 days ago)The only good use for tri-x is to check out my enlarger. It's easy to check the corner sharpness with the huge grain. I shoot Tri-X when it first was introduced in 1954 (?) and I didn't like it then.
See http://home.att.net/~nikonguy for examples of 35mm work with Tech Pan. BTW, I've decided to stop shooting 35mm B&W and plan to shoot only 6x6 and 6x7 B&W.
