Has anyone tried diluting PMK? I'm talking about 1/2 to 1/4 its normal working concentration (1:2:100).(posted 8398 days ago)I've been working on a developer formulation based on catechol and lately I've been doing some testing with higher dilution ratios. My results have yielded smoother total gradation, lessened grain clumping and remarkable sharpness. So it occurred to me that similar effects might result with more dilute PMK. Does anyone have any experience with this?
In his book, GH suggests the PMK ratio is not cast in stone, and, in fact, offers a 1:2:50 ratio to increase speed and contrast. I don't recall, however, him saying much about higher dilutions.
