It maybe a bit expensive, but I always thought it was a "one time only" developer. Others may have better idea. ted>>>>> Kodak T-max films publication F-32 gives the following processing times for Tmax developer: @75 degrees F (24 C) 1:4 Tmax 100 6 1/2 min Tmax 400 6 min 1:7 " 10 min " 10 min 1:9 " 14 min " 15 min I use the 1:7 dilution because it allows me to develop both T-max 100 and T-max 400 in the same tank for the same time and 1:4 or 1:9 doesn't allow that. I develop for 11 minutes (or 12 minutes depending on the subject material) at 75 degrees but my darkroom tends to be at about 65 degrees most of the time so the tank cools down some and I don't really vigorously agitate the tank.
