Young Teen College Girl Portrait

Two methods of obtaining photographic self-portraits are widespread. One is photographing a reflection in the mirror, and the other photographing one's self with the camera in an outstretched hand. Eleazar Langman photographed his reflection on the surface of a nickel-plated teapot.
Another method involves setting the camera or capture device upon a tripod, or surface. One might then set the camera's timer, or use a remote controlled shutter release.
Finally, setting up the camera, entering the scene and having an assistant release the shutter (i.e., if the presence of a cable release is unwanted in the photo) can arguably be regarded as a photographic self-portrait, as well.
