Wow a lot of responce. I find the claim of Anchell very strong. For him his saying is correct I suppose.
I have never used Tri-X. I use TMax 400 for my work in 35mm as well as 4x5. I test all of my films with step wedges and all that to see how a film is with my developer. I personally prefer the straightness of the curves which I see with "modern" films over that of "classical" films. I suppose to see "microscopic
variations in contrast" you need a microscope in sorts.
The general look and feel of a film of course in combination with a certain paper should fit.
There are a lot of claims and thoughts out there, some true some only in part.
Hopefully we with have both films and all others for a long time to keep everybody happy and the discussions going.
