Kodak D-76 Film Developer TM 3.8L/1US gal

KODAK PROFESSIONAL D-76 black and white film developer provides full emulsion speed and excellent shadow detail with normal contrast, and produces fine grain with a variety of continuous-tone black-and-white films. For greater sharpness, but with a slight increase in graininess, you can use a 1:1 dilution of this developer. It yields a long density range, and its development latitude allows push processing with relatively low fog.
