Lately I played with a D-23D variant; it was D-23 1:3 followed by a Borax B bath. The idea was to see if it would tone down Fuji Acros' hot high end and see how it'd do with TMX.(posted 8199 days ago)Curves for N and N-1 turned out to be virtually identical to D-76H 1:1 or 1:3, or iow, the "magic" that divided development is supposed to do sure didn't occur with those films.
