PMK development specs for new Delta 400

  1. Has anyone developed the new Delta 400 in PMK and if so, what are time and temperature that proved successful? Thanks
  2. Don: I've been developing new Delta 400 (120 format) in regular
    strength PMK in a Paterson System 4 tank for 16 minutes at 70F - gives
    me EI 320 that prints well using my dichroic (diffusion) enlarger on
    Ilford Multigrade at grade 2.


    I agitate using end-over-end inversions with continuous agitation for
    the first 30 seconds followed by 2 inversions every 15 seconds. I use
    a water stop bath for 1 minute, Formulary TF-4 fixer, 2 minute
    after-bath in the used developer, and a 20 minute wash.


    Great combination with plenty of stain, great sharpness, and grain
    that comes close to rivalling that of FP4+/PMK.
