Rated 5 out of 5

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

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.

A Great Developer

I've used Pyrocat MC in a Jobo for a number of years. I get good results on a wide range of films. The staining effect contributes to fewer printing steps. Highly recommended.

DI-13 By Phil Davis is a developer that's ideal for subjects from normal (7-stop) to extremely long (10+ stops) range when increased shadow contrast and reduced mid-tone contrast are desired. It has been formulated specifically to take advantage of the unique characteristics of Kodak T-Max 100 film and is not recommended for use with any other film material. DI-13 provides low to very low contrast with excellent shadow detail, while maintaining relatively high film speed. Not recommended for expansion development.
