First, I used the standard times, you can find them inside the filmbox: D76 1:1, 9:45

But I was not satiesfied with the results and found an advice at the Kodak-homepage. Kodakt says: "You can develop one 135-3 roll (80 square inches) in 473 mL (16 ounces) or two rolls together in 946 mL (one quart) of diluted developer. If you process one 135-36 roll in a 237 mL (8-ounce) tank or two 135-36 rolls in a 473 mL (16-ounce) tank, increase the development time by 10 percent."

Now I develop the Tri-X like this: D76 1:1, 10:40. The results are much better. So, for the T-Max 400 I do it in the same way: 10 percent more... D76 1:1, 13:45

Good luck, Alex
