Classical Realism is characterized by love for the visible world and the great traditions of Western art, including Classicism, Realism and Impressionism. The movement's aesthetic is Classical in that it exhibits a preference for order, beauty, harmony and completeness; it is Realist because its primary subject matter comes from the representation of nature based on the artist's observation. Artists in this genre strive to draw and paint from the direct observation of nature, and eschew the use of photography or other mechanical aids. In this regard, Classical Realism differs from the art movements of Photorealism and Hyperrealism. Stylistically, classical realists employ methods used by both Impressionist and Academic artists.
