Realism in the arts is the attempt to represent subject matter truthfully, without artificiality and avoiding artistic conventions, 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 mundane, ugly or sordid, such as works of social realism, regionalism, or kitchen sink realism.
