A while ago I decided to make some prints of a pregnant person who had posed for me, from Tri-X negs that I over-exposed. I'm even fairly sure I over-exposed them by the same two stops you did. I think I developed them in Microdol-X undiluted. I might have reduced the development time a bit, but this is a chancey thing. Too little development will yield a weird tonality. Anyway, I did not reduce time of development very much, and got very, very dense negs. The prints took quite long enlarger exposures, and the first couple of test prints were very crappy. But eventually I got the exposure right, and saw what beautiful results were possible with 'generously' exposed Tri-X. Skin tones work out gorgeously. As a matter of routine, I expose film at half the manufacturer's rating. So that accounts for one of your stops of overexposure. And a further stop is really only enough to improve shadow response. In my opinion, Tri-X is not "over-exposed" at EI 100. Different terminology would be appropriate. Avoid developing too much, but avoid too little development even more. I'd advise a developer that tends to lose speed, such as Microdol, with development time reduced ten or maybe fifteen per cent. I wouldn't dilute the developer. The prints might be better than your usual ... regards, --le ________________________________ Lloyd Erlick Portraits, Toronto. website: www.heylloyd.com telephone: 416-686-0326 email: portrait@xxxxxxxxxxxx ________________________________ -- The real problem with exposing Tri-X this way is longer shutter openings, and hence motion blur in the results. I find the combination of Tri-X at EI 200, a tripod, and Xtol diluted 1+2 just beautiful. I use exactly the same parameters for TMY.
