Following the appearance of the first daguerreotypes in the late 1830s and the subsequent discovery of techniques for making photographic prints on paper, a very close relationship was established between photography and painting. The artificial eye of the camera of photographers such as Gustave Le Gray, Eugène Cuvelier, Henri Le Secq, Olympe Aguado, Charles Marville and Félix Nadar spurred Édouard Manet, Edgar Degas and the young painters of Impressionism Camille Pissarro, Paul Cézanne, Alfred Sisley, Claude Monet, Marie Bracquemond, Pierre-Auguste Renoir, Berthe Morisot and Gustave Caillebotte to devise a new way of looking at the world.
