Traditional printing of photographic images is done either on silver coated paper, photographic color paper or digital printers. Alternative printing methods use non silver based processes, developed and used mainly in the 19th century. These printing techniques can give a photographic image a very different appearance and character. Cyanotpye uses ultraviolet light transmitted through a negative onto coated surfaces to generate prussian blue based images. It is one of the oldest photographic printing techniques.
