Amazing grainless with such a high speed film (EI 1600 for the

Yes . . . it surprised me too. TMax P3200 is actually an ISO 800 or ISO
1000 film depending on specific developing chemistry. If it's used at EI
3200, it must be P2 processed. As I understand it, the emulsion was
designed to be pushed to P2 without getting too contrasty or unduly grainy
given its speed. At EI 1600, it's comparable in granularity to Tri-X at EI
400, even though the granules will be a different shape, and it backs off
the contrast some.
P3200's data sheet has information about using it at EI 800, 1600, 3200 and
6400. The film cartridge allows marking the latter three for P1 through P3
processing plus a blank space if it's used at some other EI. Found it to
be very interesting stuff. I don't particularly care for TMax 100 or 400,
but this looks like it's completely different. I may have to shoot some
Tri-X at P2 (EI 1600) just to compare the two when used at the same EI.
