Maurice Guibert (12 August 1856 – 13 January 1922) was a French photographer best known today as a friend of Henri de Toulouse-Lautrec.
He was an agent for the champagne company Moët and Chandon and a member of the Société française de photographie. Little else is known of him other than his self-portraits and photos of Toulouse-Lautrec that often led to collaborations such as in the painting À La Mie:
Robert Demachy (1859–1936) was a prominent French Pictorial photographer of the late 19th and early 20th century. He is best known for his intensely manipulated prints that display a distinct painterly quality.
Charles Nègre (French: [nɛɡʁ]; 9 May 1820 – 16 January 1880) was a pioneering photographer, born in Grasse, France. He studied under the painters Paul Delaroche, Ingres and Drolling before establishing his own studio at 21 Quai Bourbon on the Île Saint-Louis, Paris.
Delaroche encouraged the use of photography as research for painting; Nègre started with the daguerreotype process before moving on to calotypes. His "Chimney-Sweeps Walking", an albumen print taken on the Quai Bourbon in 1851, may have been a staged study for a painting, but is nevertheless considered important to photographic history for its being an early instance of an interest in capturing movement and freezing it forever in one moment.Having been passed over for the Missions Héliographiques which commissioned many of his peers, Nègre independently embarked on his own remarkably extensive study of the Midi region. The interesting shapes in his 1852 photograph of buildings in Grasse have caused it to be seen as a precursor to art photography. In 1859, he was commissioned by Empress Eugénie to photograph the newly established Imperial Asylum in the Bois de Vincennes, a hospital for disabled workingmen.He used both albumen and salt print, and was known also as a skilled printer of photographs, using a gravure method of his own development. A plan commissioned by Napoleon III to print photographs of sculpture never came to fruition, and in 1861 Nègre retired to Nice, where he made views and portraits for holiday makers. He died in Grasse in 1880.
