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
