Quick guide to the Darkroom Automation f-Stop timer is available
To assist in evaluating the timer there is a quick guide to the Darkroom Automation f-Stop Timer at
It shows the basic steps in operating the timer, gives a feel for what it does and illustrates the steps in making burns and dodges. The quick guide doesn't cover memories or split-grade printing. The complete manual covering these topics should be on the website in a day or so. The operation shown is similar to that of the original Darkroom Automation timer, with a few exceptions.
(My version of Acrobat Reader needs to load the manual twice before it gets it right.)
