I've been a fan of D-76 for a few years and am considering trying D-23 if only to gain a better control over blank skys'. Additionally I've been using an acid free processing of Stop and TF-4 Fixing which I am pleased with.
My hesitation in trying D-23 is a potential scum left on the neg without the acid Stop/Fix routine. Do you who use D-23 work in an acid free process?
Thanks,
Yes. Plain water for stop bath, and TF-3 Alkaline Fixer.
With an alkaline fixer, there is no need for Hypo Clear. There is less washing, less water used.
Tablet films = Pyrocat
Standard films = D23
Long scale = D23 two bath
D23 loses a little film speed to D76, but I sure like the highlights better.

I'd agree that Perceptol slows the film speed, but it gave me better results with modern films like FP4. What D-23 was nice for was divided dev, going between a tray
of dev and one with just a Kodalk solution. With somewhat thicker emulsion films you
could get something analogous to water-bath dev, but much more reliable. For general
shooting I gave up on all the above (including 76) once I started using pyro - just so
much easier to print.
I have read that D23 is not recommended rotary processors like Jobo - fact or fiction?
I use D-23 for night time photography. Scenes were there is huge dynamic range and the light source might be in the image like a street light or store sign. D-23 holds the high values very well while having great shadow detail. My experience is that the developer has more grain than D-76. I am indifference about the loss of speed since my exposures are already measured in seconds and dealing with reciprocity failure. But only D-23 gives me a printable negative with night scenes. D-23 is a good tool to have in your dark room. But my favorite developer for daily use is D76 1:1.
Certainly not published by Kodak. Proposed by Grant Haist, for whom it's named. When someone on a forum refers to D-76H, one can count on it being the formula I posted.
