I have done some testing using the Phenidone version of Pyrocat HD. Note
that I mix the stock solution using distilled water, but pre-soak, final
developer dilution (just prior to using), and wash is with tap water.
Two to 5 min pre-soak. Fix is rapid fix without the acid. Times are for
normal lighting contrast. My times for most developers run 10% - 20%
higher than "book" values. I suspect this is due to the pre-soak and the
alkali quality of my tap water.
120 FP4+, 1:1:100 @ 70 deg for 9:20 yields a DR of 1.4 using the blue
channel, small tank, 30 sec inv.
120 FP4+, 1:1:100 @ 70 deg for 11:45 yields a DR of 1.6 using the blue
channel, small tank, 30 sec inv
120 TMX, 1:1:100 @ 70 deg for 12:50 yields a DR of 1.4 using the blue
channel, small tank, 30 sec inv
120 TMX, 1:1:100 @ 70 deg for 18:15 yields a DR of 1.6 using the blue
channel, small tank, 30 sec inv.
Sheet FP4+, 2:2:100 @ 70 deg for 9:20 yields a DR of 1.6 using the blue
channel, Unicolor drum and agitator.
Sheet FP4+, 2:2:100 @ 70 deg for 8:10 yields a DR of 1.3 using the blue
channel, Unicolor drum and agit.
