I use D-23 instead of D-76 when I want more compensation effect and acutance. I don't think it's a developer for all occassions. Negatives from it have a quite distinct look. It is, however, a very useful, good developer that works with just about any film. One point, though. Be careful mixing it. It is very sensitive to stray alkalai, and tap water with a slightly high pH could turn your negatives to soot.
