DEVELOPER (One Shot)
Part A
Water (de-ionized) ................ 350.0 ml
Sodium Sulfite . . . . . . . . . . . . . . 1.28 grams
Potassium Bromide ................... 0.5 gram
Sodium Carbonate (mono) ..... 12.5 grams
Part B
Water (de-ionized) ............... 100.0 ml
CD-3 . . . . . . . . . . .. . . . . . . . . . 2.0 grams
pH 10.25 . . . . . . . .. . . . . . . . . 10.25
Immediately add 'B' to 'A', add de-ionized water to make a total of 500 ml. Age one hour, but do not use after 12 hours. Loses activity after that time. For one roll, use a double 35mm tank, with a dummy reel on top. Use only 250 ml developer. Agitation: Vigorous agitation must be avoided or overall density and contrast will increase to an unwanted level. Best method, seems to be to lift the tank from the water bath, invert and continue through 360 degrees, then set tank back in water bath. Do this once each 30 seconds. This will assure each point of the negative getting different developer and will prevent hot spots and streaks.
