Dick, I use the cold developer (I believe this relates to working
temperature) listed in L>P> Clercs second edition of "Photography, Theory
and Practice".
140 gm. Potassium Oxalate
20 gm Sodium Phosphate, dibasic
5 gm. Oxalic Acid.
into a liter of Distilled water. Dilute 1:1 to use. Development is not
instantaneous, but takes about 1 minute. Usable temperature range seems
to be @ 60 to 75 degrees F. Is it possible that the more dilute, slower
working developers are less grainy? I haven't made a direct comparison
to the old saturated solution of Potassium Oxalate, as I have been using
this developer for many years, and generally don't have the grain
problems using peroxide in the sensitizer.
Anyone else?
