All I can say about refinal is diluted 1:3 it is the most beautiful tone range imaginable with APX100.
Fair enough.

Refinal is Phenidone, HQ, Borax, Sulfite and some other stuff.

Microphen is Phenidone, HQ, Borax, Sulfite and some other stuff.

Acufine is Phenidone, HQ, Sod. Carb. and some other stuff.

Refinal and Microphen are really, really, really similar.

Acufine is ( depending on how slatternly your standards are ) similar. By the time I dilute them both to be able to use them at 15 -16 minutes, I'd guess I mean they are more alike than D-76 or Rodinal, HC-110, or Xtol.

I'm down to my last 12 packs of Refinal. It seems to mix up easier than Microphen. Due in part, I guess, to having different ' other stuff ' than Ilford's. But if you can use Refinal, and like it, you'll get along fine with Microphen.
