Quick question: Does someone have an on-line resource they can point me to regarding Pt/Pd (in my case palladium only) paper coating troubleshooting? Over the weekend I tried coating Arches 120# with a brush (soaked in distilled water) using a Photographer's Formulary kit. I'm not getting the dark areas as deep as I've seen possible, and the darks are a little "grainy" feeling... leaving me to believe I might not have humidified the paper enough, or maybe that I need to go with a glass coating rod. I have a Pt/Pd print from Ray Bidegain to use as reference. His image is super sharp with nice deep blacks, subtle luminous gradations, and none of this "grainy"/"solution didn't soak in enough" feeling that I just stumbled into.
