F-Stop timing is the logical and easy method for controlling print exposure; it is taught in the books and workshops of master printers and is ideal for the Zone System.

With the Darkroom Automation f-Stop Timer you work in stops just like you do with your camera but with 1/10th of a stop precision. You make dodges, burns and nested burns in stops that automatically track the base exposure. It is the only timer with a dedicated dodging feature. It automatically generates test strips in equal tone intervals ... and many, many more features.
