Mix fresh before use.  For tray development, use 1 part A, B, and C with 7 parts water.  For tank development take 9 ounces each of A, B, and C and add water to make 1 gallon. There are a number of formulas that are nearly identical, including Agfa 45, DuPont 1-D, and Gevaert GD-79.  Weston’s variant decreased the carbonate in C by about 25% and tripled the amount of A used when mixing the working solution.

For normal use, mix 12 parts A, 7 parts B, and 500 parts water.  If the negative material is innately contrasty, use 20 parts A and 5 parts B. Ansel preferred to mix the B solution at 1% instead of 10% for high-contrast subjects, and he then used 20 parts A and 50 parts B (1% solution) with 500 parts water.  Solution B does not keep well, but A keeps very well in a glass bottle with no air.
