Broadly defined as "the representation of reality", realism in the arts is the attempt to represent subject matter truthfully, without artificiality and avoiding artistic conventions, as well as implausible, exotic and supernatural elements. Realism has been prevalent in the arts at many periods, and is in large part a matter of technique and training, and the avoidance of stylization. In the visual arts, illusionistic realism is the accurate depiction of lifeforms, perspective, and the details of light and colour. Realist works of art may emphasize the ugly or sordid, such as works of social realism, regionalism, or kitchen sink realism. There have been various realism movements in the arts, such as the opera style of verismo, literary realism, theatrical realism and Italian neorealist cinema. The realism art movement in painting began in France in the 1850s, after the 1848 Revolution. The realist painters rejected Romanticism, which had come to dominate French literature and art, with roots in the late 18th century.
