When Tmax 100 hit the market in 1985 or 86(can't remember) I thought this was the answer. The only films I had used prior was TRI-X, Plus X and a small dap of Panatomic X. I won't count the Tech-Pan I shot. I found out real quick that I wasn't ready for this new film. I had to learn to develop differently and even tried "hot" developing it, but still didn't like it as well as Plus-X. It's a better film now, but I still don't use it. Drew, I found the same thing with FP4+ and HP5+ that you found with the two Tmax films. I shoot only 120 and find all my HP5+ shots to be sharper looking compared to FP4+ when enlarged past 16x20. I develop in Xtol-R and grain is not an issue. The HP5+ shots just seem to have that "bite" to them that FP4+ lacks. I'm certainly not saying FP4+ is bad by any means, but I just like the looks of HP5+ better. Maybe if I were using a different developer it might be the other way around? JohnW
