I have heard it both ways, that higher dilution (i.e.: 1+50) = higher acutance; and that lower dilution (i.e. 1+25) = higher acutance.
Does anyone know which is correct?
Rodinal is a high acutance developer and I would suggest the only difference in dilution strength is that the longer times provide greater possibilities for still bath development, but doubt if this makes much difference.
