tim_brown Posted December 29, 1997 Share Posted December 29, 1997 Look at the deep shadow areas of your negatives. These areas should look nearly as clear as the unexposed parts of the film. Find or make a negative with the thinnest part of the image at the edge of the frame, the edge should be just visible. This is approximately your minimum exposure for full shadow detail. A contrasty scene will need a little more exposure, a soft scene a little less. Tri-X's latitude canabsorb about two stops over exposure with little trouble, so you can shoot it at 200 or even 100 even if you might get decent shadow details at 320-400. The image will be sharper and less grainy at the minimum exposure though. <p> If you learn to read your negatives visually and adjust development and exposure in small steps you can fine tune your technique.

paul_brenner Posted January 1, 1998 Share Posted January 1, 1998 Keith, I'd suggest you purchase a book by Phil Davis called "Beyond the Zone System" and follow his simple but very effective format. You can learn more about the system from Darkroom Innovations Inc. located at www.darkroom-innovations.com on the net. Link to comment Share on other sites More sharing options...
