Forensic photographers use photography and videography to aid in documentation and reconstruction of crime scenes with specialized techniques. An example of forensic photography performed by the section is luminol blood visualization which allows crime scene investigators to see latent blood traces that are invisible to the naked eye. This technique is very sensitive and requires explicit photographic protocol to produce satisfactory results. The photographers also provide technical support to Crime Lab personnel with detailed evidence exemplars, presentations, and photographic documentation of crime scenes, including aerial views.
The section may also perform Image Enhancement which involves the application of digital techniques to isolate, clarify, or enlarge areas of interest for further examination or presentation in court.
Digital/Multimedia Evidence Audio/Video Analysis is also performed in the section and involves the digital enhancement of video and audio tapes from various formats (such as law enforcement in-car cameras, and surveillance cameras).
