Hi, I have posted a YouTube video brazenly entitled "The Zone System is Dead." It shows a method I have worked out for controlling contrast in the development of black and white film. The video is intended for photographers who process their own films. I submit that the method described is simpler and more straightforward than the Zone System. The method does require darkroom testing. I use my enlarger and a Stouffer step wedge. The method tells you how to produce (for your film and developer) your lowest and highest contrast levels, and then how to produce equally spaced contrast levels in between. Finally, it shows how to assign ASA numbers to the contrast levels identified.
