Lips, Anterior (1:3 Horizontal)

Patient position: The patient sits upright with the mouth naturally closed.

Background: A uniform background is desired. A black, blue, or gray color is ideal; however, white is acceptable.

Film: ASA 100 or 200 Ektachrome.

Exposure setting: Aperture priority mode with an aperture setting of f11 or smaller (f16 or f22).

Reproduction ratio: 1:3.

Camera position: The camera is held in the horizontal format parallel to the anterior face.

Flash position: The flash is held off-camera along the top of the barrel of the lens directed at the lips.

Plane of focus: At the level of the lips or pathology surrounding the lips.

Tips: A precise reproduction ratio of 1:3 is obtained by placing the camera on manual focus, moving the focus ring to a reproduction ratio of 1:3, moving the camera closer to or farther from the subject until the lips are in sharp focus, and shooting the photograph. Ensure that the camera is level with the lips.

Common mistakes: Shooting on program or automatic exposure mode results in an image with poor depth of field. Leaving the flash in the hot shoe results in a poorly illuminated photograph. Photographing the lips closer than 1:3 reproduction is too close for the establishing shot.
