Photographic developer orange positive mask to correct colour. In addition, there is a third type of coupler called a DIR (Developer Inhibitor Release) coupler. This coupler releases a powerful inhibitor during dye formation, which affects edge effects and causes effects between layers to enhance overall image quality. In Ektachrome-type (E-6 process) transparencies, the film is first processed in an unusual developer containing phenidone and Hydroquinone-monosulfonate. This black and white developer is used for 6:00 at 100.4°F (38°C), with more time yielding "push" processing to increase the apparent film speed by reducing the Dmax, or maximum density. The first developer is the most
