Depth of field is the distance between the nearest and furthest object in a scene that appears acceptably sharp in an image. This depends upon three things: aperture setting, focal length and distance between the camera and the subject. The DOF is determined by the camera-to-subject distance, the lens focal length, the lens f-number, and the format size or circle of confusion criterion. It is one of the most creative and profound effects available to photographers.
