Fine art nude photography is a genre of fine-art photography which depicts the nude human body with 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. Erotic interest, although often present, is secondary, [1] which distinguishes art photography from both glamour photography , which focuses on showing the subject of the photograph in the most attractive way, and pornographic photography , which has the primary purpose of sexually arousing the viewer.
