How should a forensic technician photograph a bite mark on a victim?
What will be an ideal response?
1. An orientation (medium) view of the bite mark should be taken first so the viewer of the photo(s) is aware of the location of the bite mark on the victim. A close-up photo of the bite mark is taken after completion of steps 2–10.
2. Secure the camera on a tripod.
3. The camera should be placed directly in front of the bite mark with the surface of the camera lens parallel to (facing) the mark.
4. A L-shaped ruler (measuring device) should be placed against the skin, next to the bite mark.
5. The camera's aperture setting should provide the best depth-of-field possible. An F-stop setting of F-22 is recommended.
6. If using a digital camera, the frame should be filled with the details of the bite mark as well as the ruler, rather than photographing the bite mark one-to-one (life size).
7. The camera's flash unit should be held at a 45-degree angle to the bite mark. A series of photographs should be taken, bracketing (using different shutter speeds to allow in different amounts of light) if necessary.
8. ALS photography may also be conducted.
