I've had good experiences with Photographer's Formulary products since 2012
This time I bought my Pyrocat-HD in Glycol from Adorama for convenience sake. I've had good experiences with Photographer's Formulary products since 2012 and have had consistent success with them. "Shiprock" was developed using a dilution of 1.5:3:100 in a Jobo 3005 Expert drum and a Jobo CPP3 processor operated at 55 RPM.
I say give it a try
Excellent stuff. Easy to mix and use. A great way to get a different look from your black and white film. May not be everyone's cup of tea, but definitely worth a try for experimentation's sake and to try and get closer to your artistic vision as a film photographer
The PMK formula was developed by Gordon Hutchings and is designed as a universal developer for a wide variety of modern emulsions used under diverse conditions. PMK stands for "Pyro-Metol-Kodalk". Kodak has changed the name Kodalk to Balanced Alkali - this is their proprietary name for sodium metaborate. The formula is constituted to achieve the best overall results in consideration 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.
An alkaline fixer solution such as TF-4 (see page 11) is recommended for achieving maximum pyro stain on the negative. A conventional rapid fix may diminish staining effects of pyro and PMK formula. The PMK formula consists of two stock solutions. The "A" stock is the developer agents and the "B" stock is the alkali or accelerator.
