Dirty Gummy Faces

My work involves an old wet photographic printing process, gumbichromate. I hand paint each print, sometimes with more than one coat. In the process I leave brushstrokes adding to the mystery and atmosphere of the portraits. I choose how I print each images to bring out the qualities of the protrait I want to enhance Each original image is quite large, 30 by 20 inches, and is completely unique, or should I say 'non fungible'
