Product Features
This universal film developer was developed by renowned darkroom technician and fine-art printer Gordon Hutchings. PMK stands for Pyro-Metol-Kodalk (although Kodak has changed the name "Kodalk" to "Balanced Alkali") and has become a popular favorite among photographers in search of the following technical criteria: sharpness, maximum image stain, minimum general stain, edge effects, film speed, flexibility for Zone System Plus and Minus development, stability, repeatability, convenience of use and long shelf life.
This is the powder version of the PMK formula, consisting of two stock solutions: A-stock is the developer agent and the B-stock is the alkali, or accelerator. Stock solution dilutes to make 25 liters of working solution.
