The ambrotype is a positive on glass involving the wet plate collodion process, this method of photography is like a print on paper, it is viewed by reflected light. Each portrait is a unique one off, that can only be duplicated by photographing the image. My ambrotype portraits are made on my vintage Eastman No. 1 camera that would be c1920. Please contact meif you would like your portrait created using this beautifully evocative method.
