That's the main problem with TMax, and to a lesser extent, Delta.
They have no real toe; it just drops off the deep end. Similarly,
they don't have a shoulder like other films; once you overexpose, the
information is gone. This is a slight exaggeration, but neither the
toe nor the shoulder of these films have the gentle roll-off that
similar portions of the Tri-X or HP5 curves do.
