Walker,
Do you have a resource you can point me to regarding the use of Na2 to help eliminate chemical fog and not as a contract control agent? I have been using Na2 in tiny quantities (e.g. when printing the 129Spyder chart on Revere Platinum I use 850ul each Pd + FOx, 85ul T20/10%, and 43ul 1.25% Na2). I’ve never had problems with fogging (I am also meticulous in my clearing working) but have been curious, specifically, about testing Na2 for use in helping prevent chemical fogging; as opposed to its traditional use as a contrast agent with film negatives.
thank you.
Michael
