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.

Formulary's TD-3 Technical Pan Film Developer is an original formulation by William Troop. It is a unique, non-Phenidone based film developer offered exclusively by the Formulary. This developer, when used to process Kodak Technical Pan film. yields negatives with unique clarity, high acutance and superlative low contrast gradation. With TD-3 development there is a true increase with most developers. The combination of Tech Pan film and TD-3 allows grain less 16x20 prints to be made. An average of 20 rolls of film can be developed with the small kit, 80 with the medium size kit and 120 with the large kit. The shelf life of the stock solutions is one year, the working solution is used only once. Shipped as a liquid concentrate.
