The speed and convenience of silver-gelatin photography eventually displaced photogravure which fell into disuse after the Edward S. This publication also featured the photogravures of Alvin Langdon Coburn who was a fine gravure printer and envisioned his photographic work as gravures rather than other photo-based processes. This continued with the work of Alfred Stieglitz in the early 20th century, especially in relation to his publication Camera Work. Photogravure practitioners such as Peter Henry Emerson and others brought the art to a high standard in the late 19th century. The human eye resolves these fine variations into a continuous tone image. Unlike half-tone processes which vary the size of dot, the depth of ink wells is varied in a photogravure plate. The unique tonal range comes from photogravure's variable depth of etch, that is, the shadows are etched many times deeper than the highlights. Photogravure registers a wide variety of tones, through the transfer of etching ink from an etched copper plate to special dampened paper run through an etching press. In France the correct term for photogravure is hР“В©liogravure, while the French term photogravure refers to any photo-based etching technique.Р”В«lessed Art Thou Among Women by Gertrude KР“В¤sebier, 1899. Photogravure is distinguished from rotogravure in that photogravure uses a flat copper plate etched rather deeply and printed by hand, while in rotogravure, as the name implies, a rotary cylinder is only lightly etched, and it is a factory printing process for newspapers, magazines, and packaging. This process, the one still in use today, is called the Talbot-KliР”РЊ process.Р”В«ecause of its high quality and richness, photogravure was used for both original fine art prints and for photo-reproduction of works from other media such as paintings. Photogravure in its mature form was developed in 1878 by Czech painter Karel KlР“ВР”РЊ, who built on Talbot's research. He worked on his photomechanical process in the 1850s and patented it in 1852 ('photographic engraving') and 1858 ('photoglyphic engraving'). Talbot, inventor of the calotype paper negative process, wanted to make paper prints that would not fade.

NiР“В©pce's early images were among the first photographs, pre-dating daguerreotypes and the later wet collodion photographic process. NiР“В©pce was seeking a means to create photographic images on plates that could then be etched and used to make prints on paper with a traditional printing press. The earliest forms of photogravure were developed by two original pioneers of photography itself, first NicР“В©phore NiР“В©pce in France in the 1820s, and later Henry Fox Talbot in England.
