PMK development specs for new Delta 400


Recommended Posts

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.

 

<p>

 

Great combination with plenty of stain, great sharpness, and grain

that comes close to rivalling that of FP4+/PMK.
