Kodak's processing data for T-MAX developer show the same development times for both the normal film speed and for a one-stop push (This is true for T-Max films; I can't recall if it applies to others). In other words, T-Max is a push developer that accomplishes at least a slight increase in the actual shadow density (Maybe 1/3 stop?).(posted 8449 days ago)Another thought would be to shoot TMax P3200 instead of tri-X; but shoot it at 800 or 1000. (Its true speed is really 800). By doing this, you won't have to give up any shadow speed at all.
