I found it to give somewhat more graininess and lower acutance than D-76 1:1 or Xtol 1:1 with HP5+.(posted 8950 days ago)Although it has definite advantages for those who are into alt printing and for "heroic measures" contractions when printing on VC paper, imho it has more disadvantages than advantages.
So, I recommend D-76 1:1. Yes there are other fine-grain developers such as Microdol-X, Perceptol and D-25 but there's such a speed loss that rather than using them you'd be better off to just shoot Delta 100 and develop it in D-76 or Xtol.
