(December 6, 1750 - February 16, 1819) was a French painter. Valenciennes worked in Rome from 1778 to 1782, where he made a number of landscape studies directly from nature, sometimes painting the same set of trees or house at different times of day.He theorized on this idea in Advice to a Student on Painting, Particularly on Landscape (1800), developing a concept of a "landscape portrait" in which the artist paints a landscape directly while looking upon it, taking care to capture its particular details.Although he spoke of this as a type of painting mainly of interest to "amateurs", as distinguished from the higher art of the academies, he found it of great interest, and of his own works the surviving landscape portraits have been the most noted by later commentators. He in particular urged artists to capture the distinctive details of a scene's architecture, dress, agriculture, and so on, in order to give the landscape a sense of belonging to a specific place; in this he probably influenced other French artists active in Italy who took an anthropological approach to painting rural areas and customs, such as Hubert Robert, Pierre-Athanase Chauvin and Achille-Etna Michallon.
