Response to More Contrast out of T400CN

Mike, I think Tribletts printing experience is pointing on the right way to get the best contrast out of the "400" CN: overexposure. Or, more important, really avoid underexposure. With a rating of ISO400, you may underexpose this film. With an underexposed negative it is impossible, without selective burning, to get a full contrast range because you cannot print to maximum black without everything else look grey. And to burn wrinkles, pieces of hair or even pupils of the eyes is as good as impossible. If you rate the film at 320, 200, you are more on the safe side, you can print to maximum black and control the highlights with graded paper, multi-contrast paper, developer, etc. 2 steps overexposure (i.e. rating the film 100 ASA) surprises me but some overexposure really makes sense.
