ILFORD ILFOTEC DD-X is designed to complement the ILFORD black & white film range in-particular the DELTA PROFESSIONAL films. It ensures a good balance of fine grain, sharpness and tonal rendition producing negatives which are easy to print and allow a high degree of enlargement. Correctly exposed negatives developed in ILFOTEC DD-X have a full range of tones, with depth in the shadows, a smooth transition through the mid-tones and bright detailed highlights. Supplied as a liquid concentrate, ILFOTEC DD-X is typically diluted at a ratio of 1:4 for one-shot use. For greater economy, it can be reused but image quality may be reduced slightly.
