Which of the following is a recommended technique to photograph bullet hole evidence in glass?

Using dark field illumination is a recommended technique for photographing bullet hole evidence in glass because it enhances the visibility of features that might be otherwise difficult to discern. This method involves illuminating the subject from an angle such that only the light-scattered features are visible. In the context of bullet holes, this technique helps to highlight the edges and details of the bullet impact by reducing glare and reflection that typically occurs on the glass surface.

This approach is particularly beneficial because glass can produce distracting reflections and highlights that obscure details necessary for forensic analysis. By utilizing dark field illumination, the photographer can capture a clear image of the bullet hole, which is crucial for documentation and evidence presentation in investigations.

Other techniques may not provide the same level of clarity or could inadvertently introduce complications that obscure the critical details needed for forensic assessment.
