One of the earliest photographic printing processes, introduced by William Henry Fox Talbot in the late 1830s. Paper was soaked in salt water, coated with silver nitrate and exposed in contact with a negative in sunlight.
Salt prints have a matte surface and warm brown tones, because the image sits in the fibers of the paper. They were used until the 1850s, when albumen prints replaced them. See also calotype.
