Forensic photography equipment
The forensic photographer needs to take a lot of pictures from different angles, in color, in black-and-white, in infrared, and under ultraviolet light. For example, in a residential homicide, the forensic photos must include evidences found outside the residence, the entrance to the crime scene, the room where the body is found, other rooms relative to this room, the victim’s body from five different angles, close-ups of wounds, weapons, evidences of struggle, view of witnesses, and the autopsied body. Using infrared or ultraviolet, bloodstains can be found. Forensic photos can be small and barely visible (such as fingerprints and bite marks) or large and with lots of details (car crashes and burglaries). Pictures are taken at any time of the day (criminals are not considerate of other people’s need to sleep), anywhere (e.g. desert, playground, tunnels), and in any weather (rain or shine).
Thus, the most basic set of forensic photography equipment is several times bulkier than that of a photography hobbyist. Aside from the camera and normal lens, some important equipment and accessories are a wide angle lens, macro-lens, filters, electronic flash, cable release, tripod, extra batteries, scales, a gray card to help determine the best and most accurate exposures, and an extra camera. It also helps to have index cards, notebook and pen, flashlight, blocks of wood, and tape measure. If the forensic photographer’s job is to take surveillance images, then telephoto lenses should be added to this long list.
