I use HC-110 sometimes and think it is somewhat difficult to measure when it is so syrupish (is that a word???).
Is it recommenable to dilute it (e.g. 1+4) and then make working solutions from that? Or is it NOT recommended. It would certainly be easier to make working solution this way.
My first-choice developer, Rodinal (where you in doubt ), will not respond well to this treatment. But would HC-110?
