Response to EI of Tmax 400

With my particular camera,meter,enlarger,Tmax 400,developed in Tmax developer (with a 20% pull,for lower contrast,I'm using a condenser enlarger). I have found that an EI of 320 gives me the negative density and contrast that works well for my system.Full frame 35mm enlargements print with a 10 to 15 second enlarger exposure and a 2 or 2 1/2 filter. (on Polymax RC, longer exposures with Fine Art paper). You need to find the procedure that works for you. Each film is different, for example Tmax 100 needs an EI of 50 (again with low contrast development).
