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.

With the Photographers' Formulary Modified Windisch Catechol Film Developer, you can expect professional-grade, high-quality results every time. This superior film developer, meticulously formulated by William Troop, boasts the same chemical composition as the renowned Windisch Pyrocatechin, albeit in varying quantities.

Designed to work seamlessly with Kodak Technical Pan film, this developer delivers exceptionally fine grain, high-resolution images, and standard contrast, making it a reliable choice for photographers seeking precision and quality. The developer's unique formulation allows for an impressive degree of enlargement, making it an efficient tool for those aiming for larger prints without compromising on detail.

For optimal results, it is recommended to expose the Tech Pan film between 64-125 ASA when using this developer. The kit includes chemicals to create two stock solutions, which are then diluted at a ratio of 5:3:200 to yield a generous 40 liters of working solution.

The shelf life of Solution A extends up to six months, while Solution B remains effective for one month. To ensure you're always ready for your next project, the kit thoughtfully includes two packages of chemicals for making Solution B.

Experience the difference of the Photographers' Formulary Modified Windisch Catechol Film Developer, a testament to the brand's commitment to delivering effective, high-quality, and professional photography products.
