    PMK for 4x5 in Paterson Orbital ?

    Will PMK work properly in a Paterson Orbital ? I hear it oxidizes very quickly, so the developing / agitating in a tray could pose problems ?

    If anyone has any suggestion it'd be appreciated...

    in a word, yes

    I use PMK in a Jobo. I increase the proportion of Solution A by about 30% to compensate for the oxygenation (one of the steps recommended in the Book of Pyro and other places.)

    Works fine.

    You might find 510 Pyro or Rollo Pyro more suitable, however, and less trouble.
