You might also try Kodak's D-19, a very energetic developer that will
give you about as much contrast as you can get outside of a staining
developer. Zoe Zimmerman, whose work was featured in a recent issue
of View Camera, mentioned at the Large Format Conference in
Albuquerque that she uses D-19 for negatives she intends to print in
albumen, which requires a density range of 1.8 and above. I don't
know if D-19 is still packaged by Kodak, but if not you can find the
formula in a number of sources.
However, my personal opinion is that to get any snap in your print
with HP5+ from a really low-contrast scene you will be better off
with either ABC+ or Pyroca-HD since the effective printing DR with
these developers will be much greater than the actual DR read by a
densitometer because of the actinic stain.
