@NedL@markjwyatt Thanks, Yes Mark toned with selenium and vanadium, listed in the header, also dodge and burn and slight vignette. Colours not always accurate from the scanner, but you get the gist of it.
Very nice, I remember reading the neurologist, Oliver Sachs, amateur photography, like toning with vanadium. He writes about it in his book, "Uncle Tungsten," which is an ode to his Uncle, the element tungsten, and to the period table in general.
