What is Forensic Photography?

What is Forensic Photography? The visual documentation of many elements that can be found at a crime scene is referred to as forensic photography. Physical evidence that is either discovered at a crime scene or that has already been processed in a lab may be included, as well as the documentation of the crime scene. Crime scene photographers typically have a very particular reason for taking each image, setting forensic photography apart from other types of photography.

Given that a crime scene often contains vital information for an investigation, forensic photography is a type of record that is critical for maintaining the caliber of found physical evidence. Physical evidence that must be documented includes items discovered at the crime scene, in a lab, or used to identify suspects.

The subject, the scale, and a reference item are the three components that any forensic photograph at a crime scene must take into account. Additionally, a fair and accurate portrayal of the entire forensic photos must be provided.

Features of Forensic Photography

Common forms of photography, like artistic and creative photography, serve purposes other than forensic photography.

Crime scene photography enables us to document key features of the crime scene, such as its size, its focal points, and any tangible or intangible evidence discovered there or as a result of it. Crime scene photography aims to portray the entire tale by representing the context of the crime scene through a series of images. These images are used to document the crime scene's physical environment, including the surrounding region and any present physical evidence (e.g., entrances and exits). Furthermore, depending on the content being caught, these photos may be taken at different distances. In contrast to the conditions of a room, physical evidence (such as footprints, wound details, trace evidence, etc.) may simply call for overall and/or midrange photography. Video recordings may also be used to support photographs.

Evidence photography

This type of photography is used to capture pictures of many kinds of physical evidence that can be used as testimony in court, as a part of the case file, or by other investigators. Typically, the photos capture forensic discoveries made during the examination of different forensic disciplines. In addition to cameras and microscopes, forensic laboratories frequently employ infrared, ultraviolet (UV), x-ray, or laser radiation to represent details that are otherwise imperceptible to the human eye. It is vital, therefore, that these specifics do not affect the appearance and quality of the evidence being recorded.

Impression photography

Since they may be studied, compared, and searched through enormous digital databases, photographs of imprints like fingerprints, shoe prints, and tool marks must adhere to particular requirements. For instance, the Automated Fingerprint Identification System frequently receives fingerprint entries (AFIS).

Mug shots

For people who have been accused of a crime, mug shots are taken, and once one is made, it is instantly added to a master database along with any other information that is known about that person. Standardized lighting, background, and distance are needed to keep the quality constant. Physical characteristics (such as hair and eye color, facial hair, tattoos, etc.) are also associated and relevant if a photo line-up is needed, in addition to filed information.

Principles of Forensic Photography

The information that can be gleaned from crime scene photographs should be maximized by adhering to a few rules. The most fundamental are:

Securing the area and preventing any reorganization that would change the evidence.
Evaluation of the environment in order to modify the camera's settings as necessary.
Shooting the scene from all angles, switching to close-ups to show the relationship and placement of specific objects of interest.
Finally, photographs of the victims and the evidence should be taken, with both being highlighted and labeled. Additionally, when photographing the proof, a scale should be employed.

The Judicial Aspect and Validity of Photographic Evidence

Still, photography continues to be the typical means of providing visual evidence, despite the fact that videotaping crime scenes have become standard procedure in many jurisdictions. Swiveling the camera quickly, having inadequate lighting and focusing, and utilizing the zoom improperly are all common mistakes made when filming a crime scene.

The individual capturing the video should give a verbal description of each room and perspective of the crime scene while the other investigators and crime scene specialists remain silent.

The profiler's ability to create a psychological and behavioral profile of the offender is considerably helped by accurate crime scene pictures. As the police department compiles and presents evidence to the court, digital imaging equipment like cameras and image processing software can be valuable resources.

Procedures should be followed to safeguard the integrity of the evidence collected to guarantee that it is reliable and will be accepted by the appropriate court of law. The legitimacy of the documents might be contested if the protocols are not strictly followed. In general, after the creation of the records, unaltered images, and digital evidence must be captured.

To be sure of this, a hash value should be developed for the digital medium. As soon as the investigation officer has the evidence, it is retained, and a copy of this media should be made available for further investigation. To confirm that no changes were made after the file was opened at the lab for analysis, this hash value may afterward be compared with the hash value of the original digital media. When the alleged offender may have the ability to manipulate digital evidence or even pay the individuals involved after seizing the pertinent digital evidence, this method of handling photographic evidence is extremely effective.

The company hired for the case must maintain complete control over the chain of custody for all photos and logs. This condition guarantees that someone can attest to having access to every image used as evidence to support the testimony. Using an unchangeable storage medium and a separately controlled index for each unit can strengthen the accuracy of the data used in court proceedings.

Case Study

Forensic photography is a powerful tool used in criminal investigations to capture and document evidence from crime scenes. It can provide valuable visual evidence that can be used to build a case against a suspect, reconstruct events, and help to identify perpetrators. One such case where forensic photography played a key role in solving a crime is the investigation of the Boston Strangler murders.

Between June 1962 and January 1964, a series of brutal murders occurred in the Boston area. The victims were all women, aged between 19 and 85, and each had been strangled with a ligature. The case became known as the Boston Strangler, and it became one of the most notorious and perplexing serial killer cases in American history.

Despite an intensive investigation, no suspects were identified for several years. However, the investigation took a significant turn in 1964 when a woman named Mary Sullivan was found murdered in her apartment. Forensic photographers were brought in to document the scene, and their work would ultimately play a key role in solving the case.

The photographs taken at the crime scene were carefully analyzed, and a pattern began to emerge. The killer appeared to have used a distinctive knot in the ligature used to strangle the victims, which was visible in the photographs. Investigators were able to link this knot to several other murders, and a suspect was identified - Albert DeSalvo, a man who had previously been arrested for unrelated crimes.

DeSalvo was brought in for questioning and initially denied any involvement in the Boston Strangler murders. However, investigators were able to use forensic photography to further build their case against him. A photograph was taken of DeSalvo's hands, which revealed that he had a distinctive scar on his finger that matched a pattern found on one of the victims. Additionally, photographs of DeSalvo's home showed evidence linking him to several of the crime scenes.

Based on this evidence, DeSalvo was charged with the Boston Strangler murders. Although he initially recanted his confession, he later admitted to the crimes and was sentenced to life in prison. The investigation of the Boston Strangler case, and the use of forensic photography in particular, was a major breakthrough in forensic science and has since become a model for other criminal investigations.

The use of forensic photography in the Boston Strangler case highlights the importance of capturing and preserving evidence from crime scenes. Forensic photographers are trained to document every detail of a crime scene, including injuries to victims, bloodstains, and other physical evidence. This documentation is then used to build a case against the suspect, and it can also be used in court as evidence.

In addition to documenting physical evidence, forensic photographers may also use specialized equipment to capture images that are not visible to the naked eye. For example, ultraviolet photography can be used to detect bodily fluids, such as blood or semen, that may not be visible under normal lighting conditions.

Forensic photography is also used in crime scene reconstruction, which involves using evidence to recreate the events that led up to a crime. By analyzing photographs and other evidence, investigators can determine the position of victims and suspects, the trajectory of bullets, and other key details that can help to piece together the sequence of events.

However, while forensic photography can be a powerful tool in criminal investigations, it is important to use it responsibly and ethically. It is essential that photographs are taken without altering or damaging the evidence, and that they are carefully analyzed to ensure that they are accurate and reliable.

In conclusion, the investigation of the Boston Strangler case highlights the crucial role that forensic photography can play in criminal investigations. By carefully documenting and analyzing evidence from crime scenes, forensic photographers can help to identify suspects, build a case against them, and ultimately bring them to justice. As forensic science continues to evolve, the potential for forensic.
