Response to rating film

Donna, Down rating a film gives you better shadow detail and is usually more accurate of the films 'true' speed. I reguarly rate Delta 100 at 80, some films require more exposure to obtain better shadow detail. I also find the published development times to be too high for my tastes. If you process your own b/w films you should make a few trials to achiev negs. that you find fairly easy to print on a normal grade of paper with both shadow and highlight detail. So empty shadows ned more exposure of the film and washed out highlights need less development of the film. Good luck,
