I've watched this thread continually pop up, read a post or 2, and moved on. It seems a continuing saga of experiments to make Rodinal palatable. Now I see added salt is one of the tricks to make this grain factory workable. It's always about the grain with this potion, isn't it? So now it seems that high dilution and salt is another way of trying to make Microdol out of this developer. To which I can only question. why not just use Microdol (or Perceptol)? Maybe I'm getting old and have fewer days, so to me, life's too short to make a bad developer work.
Or use a fine-grain film. Of course it's grainy with HP5.
Acros, TMX, Pan-F and Efke-25 are all awesome in Rodinal.
