Hi Mark ... Sorry for the delay in getting back to you.

Interestingly, I don't see > the grain problem nearly as much in chromogenic B&W. Chromogenic B&W is more like color film, that's why you don't see the problem as you do with B&W negative. I've scanned mostly Tri-X (old and current versions), Agfa APX 100, Iford HP5+, and maybe some Delta 100. I don't use T-MAX film, so I've no comparison or point of reference. Usually the scans are at 4000ppi, GEM, ROC, and ICE are off, and the scans are done without any manipulation.
