I "piped" in as your statements were so interesting...
See the first page of this thread. The issue I was responding to was whether T-Max films had 'inferior' tonality because they have 'less silver'. I never liked the H&D curve of the original version of T-Max 400, because it was the opposite of that of most 'outdoor' films (which have steep slopes at the foot, and soft slopes at the shoulder, which helps boost contrast in shadow regions to offset the effects of lens flare, while keeping clouds from blocking up). T-Max 400 was designed as a 'studio' film, and like others (such as TXP and the late PXP) it has a softer slope in the shadows and greater contrast in the highlights. I did not know this at first, so I was disappointed with the 'look' of TMY and quit using it (I am an 'outdoor' photographer). The revised version of TMY is supposed to have an H&D curve that is more like Tri-X Pan, though I have not used it.
