Kodak D-72 is a developer for black & white enlarging papers, producing a neutral or cold tone image. It has high capacity and a uniform development rate.
To make a stock-solution.
Water, at about 50*C. 500 ml
Metol developing agent. 3 grams
Sodium sulphite, anhydrous. 45 grams
Hydroquinone. 12 grams
Sodium carbonate, anhydrous. 67.5 grams
Potassium bromide. 2 grams
Water to make 1 litre.
Dilute the stock-solution 1+2 with water. For a higher contrast, dilute 1+1 with water. Development times are usually around 1.5 to 3 minutes depending on the paper type used.
This developer is described by Ansel Adams in "The Print" as being very similar to Kodak Dektol as sold in dry powder form.
For warmer tones, dilute 1+3 or 1+4 and add 8 ml of a 10% potassium bromide solution to each litre of working strength developer.
