You probably want the Photographer's Formulary for strange chemical concoctions. I tried "Divided D-76" but I didn't use distilled water, so the chemicals didn't work right. I have learned my lesson since then. :-)(posted 9037 days ago)They have a few divided formulas, so you will have to go and experiment. Since I started using Xtol, though, I haven't felt the need to try the alternate chemicals.
