Developer! I'm also working on some new developers using some new materials
that I have heretofore not seen referenced as a developer. I am still
undecided whether or not I will publish the ingredients or not. I'm not
being cagey as I am in business and it's my livlihood. I have noted that
some formulations of developers can use a lot of No 2 and produce little
grain. I have still to unpack my reflecting densitomter and my stepwedges
just arrived. My move from LA is still having its effects of a lot of
"whereisitat?", and whydoesntitwork?"
Anyone using any unusual developers for pt and pd? A lot of things work,
like citric acid for instance.
