When you use the film, the differences appear. I develop much less
than the longest time shown. The point is that you CAN easily see the
differences. Kodak brought out Polymax paper specifically to combat
the problem. Now that Kodak is out of the paper business, they may
have adjusted the curve of TMY to work better with other papers. After
all, Tri-X Pan does sell better. TMY is 20 years old!
