Railroad bridge over the Potomac River just outside Shepherdstown, WV, taken from the C&O Canal NHP, Maryland. The print is platinum/palladium printed over gum bichromate. The gum layer is Indian red.
I like the effects this created very much. I do gum printing and Pt/Pd printing, but have never tried pt/Pd over gum. Any advice? Choice of paper? Nice work all around.
