Has anyone experimented with two-step development? I was thinking of trying to stand develop APX100 first in extremely dilute Rodinal (1+350?) without any agitation whatsoever, but perhaps with a little sodium sulfate, for say 15 min to develop the shadows. Then give it a water rinse and transfer to Xtol or Microdol-X to develop the full tonal scale. Then another rinse, and over to TF-3. Should I spend time on this -- is it even worth trying?
