Don.

Using 1ml dichromate per liter for the print, it takes 18 minutes to develop a N negative in WD2D. Using 4ml it takes 12.5 minutes. I don't think I could do a N+ negative with no dichromate or the 1ml per liter stock. Using 5% dichromate: the difference from 1ml to 4ml is significant.

Standardizing on the 4ml dichromate per liter developer stock, I can proof with AZO, if I flash the print and use a water bath.
