Rollei Supergrain is a modern, high-performance film developer for any type of black-and-white film. Supergrain delivers superior image quality with an extremely fine grain. It produces extreme sharp results, making full use of the nominal film speed and thus can be seen as a high-compensating film developer. Virtually any black-and-white film exposed at their nominal film speed has the same developing time.
Supergrain is the result of the further development of the classic AM-74 film developer formula.
