Fingers, Dorsal, 5 (1:6 Horizontal)

Patient position: The patient sits or stands with his or her fingers placed on a flat surface such as a mayo stand. Alternatively, the patient may stand behind a gurney with the head elevated at 45°, placing the fingers flat on the inclined surface. The fingers should be spaced evenly. A pencil or pen may be used as a spacer.

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: 1:6.

Camera position: The camera is held in the horizontal format on a plane parallel to the dorsal fingers.

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

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

Tips: A precise reproduction ratio of 1:6 is obtained by placing the camera on manual focus, moving the focus ring to a reproduction ratio of 1:6, moving the camera closer to or farther from the subject until the fingers are in sharp focus, and shooting the photograph. Ensure that the camera is on a plane parallel to the fingers. 

Common mistakes: Leaving the flash in the hot shoe does not evenly illuminate the hand and casts unwanted shadows. With the flash placed under the barrel of the lens, the shadows fall underneath the hands out of sight. Remove any jewelry from the field of view unless they are part of the pathology or injury. Using the automatic or program exposure modes may produce photographs with poor depth of field.

 

 

Finger, Dorsal (1:3 Vertical)

Patient position: The patient sits or stands with his or her fingers placed on a flat surface such as a mayo stand. 

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 vertical format on a plane parallel to the dorsal finger.

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

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

Tips: Shoot an establishing shot with an adjacent finger for comparison with the diseased or injured finger. Then shoot the diseased or injured finger alone. 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 finger is in sharp focus, and shooting the photograph. Ensure that the camera is on a plane parallel to the finger.

Fingernail, Dorsal (1:1 Vertical)

Patient position: The patient sits or stands with his or her finger placed on a flat surface such as a mayo stand. 

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: 1:1.

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

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

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

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

Common mistakes: Leaving the flash in the hot shoe does not evenly illuminate the hand and casts unwanted shadows. With the flash placed under the barrel of the lens, the shadows fall underneath the fingernail out of sight. Remove any polish from the nail unless it is part of the pathology or injury. Using the automatic or program exposure modes may produce photographs with poor depth of field.
