The 'Stop System', co-written by Pierre-Yves Mahé, Richard D. Zakia, and Gordon Brown, is a simple and direct method to learn and master B&W darkroom printing. Professionals apply the Stop System for Color and B&W assignments in the studio. The method is indispensable for the amateur who desires to control his B&W printing from the outset, or the professional who seeks to adopt a simple, direct, and highly visual photographic method.
