Stand development with PMK and Xtol

[David Bigeleisen]

I've begun experimenting with stand development. My first try has been with R09, sometimes known as Rodinal. So far,so good. Has anyone tried stand development with PMK? If so, what dilution and development times are you using?
I have the same question for Xtol.
I'm developing Ilford FP4+ in a closed tank.

Thank you in advance.

PMK is not a good candidate for stand. Its very high aerial oxidation rate mandate nearly constant agitation to avoid staining.

If you want to try stand development with a staining developer, both 510 Pyro and Pyrocat-HDC do this well (once you master stand techniques for things like film suspension).

You have to agitate PMK every 15 seconds or you get uneven, mottled development. This is a known fact. You simply cannot use PMK for "stand" development.
