Dan,

Please, why are you back to D-23 (your version of it) after using so many other developers?

I'm a minimalist to start, so metol plus sodium sulfite. I like
the look of the negatives, good gradation and compensation,
from a one bath developer. D-23 or my close clone, 8-80 grams,
at a 1:7 dilution is slow working; Acros-16 minutes with
3 inversions every other minute.

A few days at most prior to processing I compound it
1-10 grams metol-sulfite, then split to two small
bottles. Each 120 roll, 500ml. Dan

Thanks, Dan.

D-76H has rather poor storage characteristics, according to this study: http://www.udmercy.edu/crna/agm/phenvitc.htm. It's probably because it lacks the "self-replenishing" effect of hydroquinone reacting with the base.
