The Process of Crime Scene Photography

In crime dramas or TV series such as "CSI," photographers flood the scene, snapping numerous photos of the crime area. They maneuver their cameras in every direction while investigators exchange theories amidst the constant flashing of camera lights. But what does crime scene photography truly involve? Given its role in documenting evidence for court proceedings, it’s far from a random process.

Forensic photography, also known as crime scene photography, has existed nearly as long as cameras have. Early criminologists recognized the potential of this technology to capture moments in time, providing an ostensibly indisputable record of a crime scene, evidence, or even a victim. Alphonse Bertillon, a 19th-century French photographer, pioneered systematic crime scene documentation. He employed methods like capturing images from multiple distances and angles, including ground-level and overhead shots.

In modern times, forensic photography plays a crucial role in both investigating and prosecuting criminal activities. This is due to the transient nature of most evidence: fingerprints need to be collected, bodies must be removed and autopsied, and properties must be restored to their original condition. Photos serve to preserve not only ephemeral evidence—such as the pattern of a bloodstain that will soon be cleaned—but also the arrangement of objects within a space and the spatial relationship between evidence and other items. These images can become invaluable to investigators long after the crime scene has been cleared.

Types of Crime Scene Photos

Crime scene photographers must approach their tasks with precision and thoroughness. They cannot overlook critical evidence or produce images that might be deemed deceptive in a legal setting. Additionally, they face the pressure of the entire investigative process. Before any evidence is handled or moved by other CSI personnel, and even before the medical examiner can take the body, the forensic photographer must meticulously capture the scene.

Forensic photography is categorized into three types: overviews, mid-range shots, and close-ups.

For indoor crime scenes, overviews encompass photographs of the building's exterior, entry and exit points, and images that situate the structure within its environment. Pictures of onlookers can later assist in identifying potential witnesses or suspects. Overviews also feature photos of every room, captured from above and from all corners.

The photographer then focuses on crucial evidence, capturing mid-range shots that depict items like a weapon within their surroundings. These images show the relationship between the evidence and other elements, such as furniture or bloodstains, while also indicating the spatial arrangement of objects in the room.

Lastly, the photographer meticulously records evidence through close-up images. These shots highlight identifying features, such as scars on a body or serial numbers on a bloodied device. A ruler is often included to provide scale, but a duplicate image without the measuring tool is always taken to prevent legal disputes over obscured details.

Naturally, photographs hold no significance without proper context. A forensic photographer maintains a detailed photo log, recording essential information such as the photo number, applied filters, time, date, location, and a description of the subject. The rise of digital photography has streamlined and enhanced the accuracy of documenting time and date details.

What tools does a forensic photographer require to document a scene effectively? And what criteria must a photograph meet to be admissible in court? Discover the answers in the next section.

Crime Scene Photography Equipment

In the past, detectives relied on sketches to document crime scenes. Photography revolutionized this process by offering more realistic and trustworthy representations. While a well-executed photograph can accurately capture the original state of a crime scene, it is also possible to manipulate images or present a version that deviates significantly from reality.

To be effective, crime scene photographs must meet specific technical criteria: proper exposure, clear focus, and optimal depth of field, ensuring the sharpness of the image. The photo must also be free from distortions. These standards ensure that the images genuinely assist investigators in their work.

For a photograph to be admissible in court, it must meet additional requirements. The image must not alter the scene or evidence, such as by obstructing key details with measuring tools or using a shallow depth of field. The photo must be relevant to the case and crafted with technical accuracy, avoiding any emotional bias.

While photographers may customize their equipment based on personal preferences or the nature of the crime scene, certain essentials are universal: a camera (often multiple), filters, electronic flashes, lenses for various shot types, a tripod, a measuring tool, a gray card for accurate exposure, and protective gear for harsh weather conditions.

While crime scene photographers typically rely on color images, black and white photography can be advantageous for capturing evidence where texture, such as latent fingerprints, is more critical than color.

Crime Scene Photographs as Art

In 2001, a remarkable discovery was made in a city records warehouse by police officers and artists. They unearthed a collection of forensic photo negatives from the Los Angeles Police Department, some dating back to the 1920s. These images captured everyday crimes, as well as some of the city's most notorious murders and significant arrests.

Captivated by the cinematic quality of many images, the artists and officers initiated a project to preserve the deteriorating negatives. They organized an exhibition that toured the United States. A lieutenant involved in the project noted that the artistic nature of the photos stemmed from less stringent forensic standards of the past, where photographers occasionally adjusted crime scenes for dramatic effect, resulting in images that, while evidential, resembled art more than modern forensic photography.

The connection between art and crime scene photography is longstanding. Weegee, a New York City freelance press photographer, became renowned for his candid and sometimes ironic depictions of crime scenes, news events, and movie premieres. In 1941, he held a solo exhibition titled "Weegee: Murder is My Business" at the Photo League in New York.

The fascination with crime scene photography is understandable. These often grim images, set in ordinary locations like steakhouses, parlors, or streets, evoke a morbid curiosity. They blend the familiar with the unsettling, creating a stark contrast that captivates viewers.
