Brightening the DarknessĮxperienced photographers often use a technique called “painting with light” to expose image details in dark or near-dark conditions. Lastly, white balance allows the camera to record the proper temperature of light, resulting in an accurate representation of the color tones of objects in the photograph. Depth of field is the amount of area in front of (foreground) and behind (background) an object that remains in focus.

Aperture refers to the size of the opening that lets light into the camera and shutter speed is how long that opening, or shutter, remains open.

Photographers use several means to tell the camera how to capture the image including aperture, shutter speed, depth of field and white balance. That said, many of today’s digital point-and-shoot cameras have a variety of settings that, with some basic operator training, allow for proper documentation.

Larger agencies may have specially trained and certified crime scene photographers with high-end cameras and lighting to document crime scenes and evidence, but more often the first responder needs to do what they can with equipment assigned to them. This makes photography a critical first responder skill. Some may consider photography more of an art than a science, but well-taken crime scene photographs can aid scientists, investigators and members of the court in their search for the truth.

Relatives noted that the victim did not drink beer. It was later discovered that the victim had a receipt for a six-pack of beer, matching the beer shown in the photograph of the refrigerator. For example, a photographer in Florida shot the inside of every cabinet and the refrigerator at a homicide scene in a home, just as a matter of procedure. The purpose of crime scene photography is to document what is there and where it is in relationship to the scene, whether it is obviously connected to the crime or not. It can consist of thousands of photographs and hours of work.Ĭrime scene photography should not just focus on the obvious. The amount of time spent depends on the size and complication in the crime scene, how much there is to document and environmental factors like weather or danger to the investigative team. There is no prescribed length of time it takes to photographically document a crime scene.
