Hola Gusi, Mi espanol no es beuno, necesito estudiar mas. Dos libros muchas excelente es "The Art of Photography" by Bruce Barnbaum, y "Creative Black and White Photography" by Les McLean. Bruce hable por trabaja con negative. Les (now my Spanish fails me) teaches very good nuances of dealing with exposure as well. You can't go wrong with either book. If you ever have the chance, bothe men teach excellent classes. Bruce concentrates more on the manipulation of the exposure and development of the negative, and Les more on the printing aspect of any negative. In my opinion, they should teach back to back courses.

A note about poor Hansbeckert. He has been driven off many forums for his antics, es loco in la cabeza.
