Cheek, Anterior (1:4 Vertical)

Patient position: The patient sits upright and looks straight ahead.

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: 1:4.

Camera position: The camera is held in the vertical format on a plane 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 anterior cheek.

Plane of focus: At the level of the anterior cheek or the level of the pathology.

Tips: A precise reproduction ratio of 1:4 is obtained by placing the camera on manual focus, moving the focus ring to a reproduction ratio of 1:4, moving the camera closer to or farther from the subject until the lateral cheek is in sharp focus, and shooting the photograph. Ensure that the camera is level with the cheek.

 Common mistakes: Leaving the flash in the hot shoe results in a poorly illuminated photograph. Remove all makeup and jewelry when possible, unless they are part of the pathology or injury.

 

 

Cheek, Lateral (1:4 Vertical)

Patient position: The patient sits upright and looks straight ahead.

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: 1:4.

Camera position: The camera is held in the vertical format on a plane parallel to the lateral face.

Flash position: The flash is held off-camera along the same side of the barrel of the lens as the front of the patient's face, directed at the lateral cheek.

Plane of focus: At the level of the lateral cheek or the level of the pathology.

Tips: A precise reproduction ratio of 1:4 is obtained by placing the camera on manual focus, moving the focus ring to a reproduction ratio of 1:4, moving the camera closer to or farther from the subject until the lateral cheek is in sharp focus, and shooting the photograph. Ensure that the camera is level with the cheek.

Common mistakes: Leaving the flash in the hot shoe results in a poorly illuminated photograph. Remove all makeup and jewelry when possible, unless they are part of the pathology or injury.

 

 

Cheek, Oblique (1:4 Vertical)

Patient position: The patient sits upright and looks straight ahead.

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: 1:4.

Camera position: The camera is held in the vertical format on a plane parallel to the face.

Flash position: The flash is held off-camera along the top of the barrel of the lens as the front of the patient's face, directed at the oblique aspect of the cheek.

Plane of focus: At the level of the cheek or the level of the pathology.

Tips: A precise reproduction ratio of 1:4 is obtained by placing the camera on manual focus, moving the focus ring to a reproduction ratio of 1:4, moving the camera closer to or farther from the subject until the oblique aspect of the cheek is in sharp focus, and shooting the photograph. Ensure that the camera is level with the cheek.

Common mistakes: Leaving the flash in the hot shoe results in a poorly illuminated photograph. Remove all makeup and jewelry when possible, unless they are part of the pathology or injury.
