D23, due to it's high sulfite content will give you "soft" grain... a beautiful developer but not fine grain or not high acutance at all. Divided D76 for extremely fine grain or for a snappier higher acutance (sharper finer grain) use Diafine. The nice part of the split bath developer is that they are compensating (develop the highlights only to a point) making printing easier and negatives that are developed to perfection. Stick with Pan F, it is beautiful also!!!(posted 8196 days ago)
