Kodak Professional D-76 is a classic black and white film developer offering fine grain results along with full film speed, high shadow detail, and normal contrast. This powdered developer contains enough chemistry to make 1 gal of working solution, which can be used straight or diluted 1:1 for increased sharpness with slightly more graininess. The developer's ability to produce a long tonal scale with low fog also benefits its use for push processing.
