High capacity, clean working, fast acting. Provides higher than normal contrast and speed, higher than average graininess.
This is a high-contrast developer with good keeping properties and high capacity. It is especially recommended for continuous-tone scientific and technical work that requires higher-than-normal contrast. This developer has special applications for reversal processing. Similar formulation Kodak D19b. When needed replenish with D19R.
