An art form that began in the late 1960s, photorealism, or superrealism, stresses photographic accuracy of image, focusing on illusionistic rendering of three-dimensional objects on a flat picture surface. International in scope, photorealism was the successor to pop art. The some of the more famous practicers of photorealism in painting include the American artists Chuck Close, Richard Estes, and Alfred Leslie. These artists have chosen as subject matter such features of contemporary American life as advertisements, or city streets.
