Salted paper prints were the earliest photographic prints on paper. They are often distinguished by their lack of precise image details and matte surface. Salted paper print images are embedded in the fibers of the paper, instead of being suspended on the surface of the paper, as in the later albumen prints and gelatin silver prints. Salted paper prints were "printed-out" in contact with paper negatives; the image was formed solely by the action of light on metal salts, without chemical developers. The printing-out process required long exposure times for producing a positive print. The process for making salted paper prints was developed by William Henry Fox Talbot in the 1830s, and salted paper prints were common until the mid-1850s, when they were eclipsed in popularity by albumen prints.[1]
