WD2D Formula
Leo,
Here is the WD2D formula FYI:
Wimberley WD2D
Stock Solution A
Water (100° F or 38° C) 400 ml
Metol 1.5 g
Sodium bisulfite, anhydrous 5 g
Pyrogallol 15 g
Water to make 500 ml
Stock Solution B
Water 400 ml
Sodium carbonate, monohydrated 22 g
Water to make 500 ml
For use, add 20ml A and 20ml B to 400ml water. To adjust contrast, vary the amount of solution B more B gives higher contrast, less B decreases contrast. The original formula contained benzotriazole, but this was later eliminated to increase contrast and reduce development times.
Hope this helps,
