The nude provides an emphasis on form, composition, emotional content, and other aesthetic qualities. The nude has been a prominent subject of photography since its invention, and played an important role in establishing photography as a fine art medium. The distinction between fine art photography and other subgenres is not absolute, but there are certain defining characteristics.
