Photographers' Formulary

Photographer's Formulary 120ED High-Contrast Paper Developer, is a catechol paper developer that is similar in composition and results to the Edwal 120 developer. Formulary 120ED produces neutral to cold tones with very high contrast (1/2 to one grade higher than normal). In addition, rich deep blacks with an abrupt tonal range can be expected. The chemicals provided, yield a stock solution that is diluted to make the working solution. While the stock solution is stable for three (3) to four (4) months, the working solution has a high capacity but limited life.
