Ilford Developer Ilfotec DD Starter 1L - The addition of **ILFOTEC DD STARTER **turns the working strength ILFOTEC DD replenisher into a machine tank developer. In a replenished developer system, ILFOTEC DD STARTER reduces the activity of the fresh developer to simulate a "seasoned" developer, i.e. one where the by-products of development are present in a stable equilibrium. Therefore, preventing a reduction in speed and contrast as the fresh developer becomes "seasoned". For mixing instructions and development times, please refer to the technical data sheet.
