TFC, this is especially pleasing to me. The decay in the iron is "mature", the lines and designs, and the dark feeling in a sunny atmosphere. What a target-rich environment that shouts loudly from these images.
For the Tri-X 400, I've been doing my Pyrocat HD at 1:1:100, 14 mins @ 75F (23.8C) in my Jobo CPP2+. It's just a tweak off the Massive Dev Chart recommendations. The reason I go with the 75F is that in the summertime, that's the coolest water I can get out of my pipes without investing in a line chiller. My darkroom is too small and doesn't have the electrical facility to sustain such a device, and I wouldn't want to pay the electric bill for running one all the time either.
Thanks. Not sure how different TX320 is from Tri-X 400. I have boycotted Kodak products for close to 40 years so have little experience with the new stuff. Someone gave me the TX320.
