Nue photography is a style of art photography which depicts the nude human body as a study. Nude photography should be distinguished from erotic photography, which has a sexually suggestive component. Many photographers consider nude photography to be a style which studies the human body, rather than the person. A photograph of a person that is meant to be recognized is called a portrait, and nude photographs often do not show a face at all. Nude photography is generally not a snapshot, but a composed image of a person in a still position. As an art form, nude photography is a stylised depiction of the nude body with the line and form of the human figure as the primary objective. Photographers sometimes use extremes of light and shadow, oiled skin, and shadows falling across the body to show texture and structure of the body. Nude photography should be distinguished from nudity in photography, which is much broader, and does not necessarily claim any artistic merit.
