The subject of the zone system is now very much in the mainstream among amateur as well as professional photographers. This newly revised edition of a photography classic teaches photographers how to recognize the zones both on the print and in the field or studio, to pre-visualize their photograph and expose accordingly, to access their prints and negatives for contrast, and to test equipment for reliable results. This book has been updated to include information on the latest developers and films. New illustrations have been added to reflect the most contemporary photographic styles, and information on digital imaging supplied in the second edition has been expanded into a new chapter. The practical approach of this book, with its numerous time-saving development and film charts and easy-to-follow testing methods, is an important resource for the beginning, large-format, 35mm, and professional photographer.
