Response to developing time for tmax400 pulled to 100

I have exposed Tmax 400 at 150 or 100 speed for the past 6 or 7 years. I have found that for a normal developer such as D-76, or T- max developer, development time is decreased approximately 2 minutes per stop of overexposure, so if your normal development time is 12 minutes, 8 minutes should be a sufficient pull-back for your higher values. You will find that your negatives have compressed contrast, so expect to be printing on a grade 3-4 paper (or filter) for a normal contrast look.
