Buttocks, Gluteals (1:10 Horizontal)

Patient position: The patient stands upright with the arms out of view.

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: 1:10.

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

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

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

Tips: A precise reproduction ratio of 1:10 is obtained by placing the camera on manual focus, moving the focus ring to a reproduction ratio of 1:10, moving the camera closer to or farther from the subject until the gluteals are in sharp focus, and shooting the photograph. Ensure that the camera is level with the gluteals. With the camera held on a plane parallel to the gluteals, a 1:10 reproduction ration is difficult to obtain when the patient is prone on the gurney. Have the patient stand whenever possible to photograph the gluteals.

Common mistakes: Leaving the flash in the hot shoe does not evenly illuminate the gluteals if a 60-mm macros lens or less is used. Remove distractions such as clothing patient gown, and jewelry from the field of view unless they are part of the pathology or injury. 

 

 

Buttocks, Gluteal cleft (1:4 Vertical)

Patient position: The patient stands upright with gloved hands retracting the gluteals away from the cleft.

Background: The gluteals provide the background for this view.

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 gluteal cleft.

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

Plane of focus: At the level of the gluteal cleft or 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 gluteal cleft is in sharp focus, and shooting the photograph. Ensure that the camera is level with the gluteal cleft. Shoot an establishing shot of the gluteal cleft without retraction.

Common mistakes: Leaving the flash in the hot shoe does not evenly illuminate the gluteal cleft. Remove distractions such as clothing patient gown, and jewelry from the field of view unless they are part of the pathology or injury. 

 

 

Buttocks, Anus (1:4 Horizontal)

Patient position: The patient is placed in the semilithotomy position, appropriately draped. The patient retracts the gluteals away from the anus with gloved hands.

Background: The gluteals and perineum provide the background for this view.

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 horizontal format on a plane parallel to the anus.

Flash position: The flash is held off-camera along the top of the barrel of the lens directed at the anus. The center of the frame is the anal opening.

Plane of focus: At the level of the anus or 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 anus is in sharp focus, and shooting the photograph. Ensure that the camera is level with the gluteal cleft. Shoot an establishing shot of the anus without retraction.

Common mistakes: Leaving the flash in the hot shoe does not evenly illuminate the anus. Remove distractions such as clothing patient gown, and jewelry from the field of view unless they are part of the pathology or injury.
