PMK development specs for new Delta 400 : LUSENET : B&W Photo - Film & Processing : One Thread

Has anyone developed the new Delta 400 in PMK and if so, what are time and temperature that proved successful? Thanks

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.
