Bench notes
ILFORD ILFOTEC DD-X Developer 1L
ILFOTEC DD-X is a liquid concentrate developer designed to complement the ILFORD black-and-white film range, especially DELTA PROFESSIONAL films. It gives a practical balance of fine grain, sharpness, full film speed, and a broad tonal range. For the cleanest one-shot workflow, dilute 1+4 and follow the official time and temperature table; it can also be reused for economy with a small reduction in image quality. Suitable for spiral tanks, dishes, trays, and rotary processors. Dispose used chemistry according to local rules.
