Forensic photography has evolved as a crucial method to visually document a crime scene for records and investigation. And if your mind is leading you to think of it as a cool and intriguing profession, then hold on! This kind of photography isn’t charming, it isn’t about capturing the picturesque.
Forensic photography, also known as crime scene photography is the creation of visual records of accidents, crime scenes and the like for measurement, analysis, investigations and as permissible evidence in the court of law. It is defined as the activity that documents the original appearance of the incident scene along with the available physical evidence.
The three elements that are compulsorily taken into consideration in forensic photography are – subject, scale, and a reference object. Crime scene photography is no child’s play. Such photographers bear the onus of representing a crime scene in the exact way how it appears originally. They need to ensure that the subject is properly focused and that there is no alteration of the colour that may mislead the investigators or juror.
Additionally, photographs need to be clicked keeping a scale or ruler next to the focused object. This enables investigators to resize the image in order to precisely reconstruct the scene.
And then there are overall photographs and medium-range photographs. Whereas an overall photograph is meant to provide a complete summary of the incident scene such as the position of evidence and original condition of the scene, a medium-range photograph aims to document the appearance of the object in question.
Care must be taken by the forensic photographer to adjust the lighting and other photographic parameters in a way that the photograph is an accurate representation of what is visible to the naked eye.
The science that interprets the contents of the image is forensic image analysis. Some companies have resulted in inefficient equipment that cut costs and speed up the investigation. The equipment is designed to perform a comparison of photography, content analysis, photogrammetry (use photos to make measurements) and to authenticate images.

Through various techniques, mega data, pixel aspect ratio, and errors are used to extract information from videos, photos, and animations. It is effective even when an individual has attempted to jam-proof.
One of the newer tools is video forensics, which is primarily a scientific examination and evaluation of multimedia evidence in legal matters.
The goal of this technology is to produce an accurate picture of the evidence to a judge and jury to help determine the verdict in a civil or criminal case.
Additionally, this technology processing techniques to enhance video footage, grainy photos refined, and to improve a particular person or object in a video, plus it converts digital video into a special format for forensic analysis. This type of work is important in solving the case for law enforcement, security, surveillance and even military operations.
A forensic investigation is done in a legal way, to establish the facts and the evidence have been examined thoroughly, considering the chain of custody, which will be presented in the courtroom.
While a quick walk through a rural police department might not reveal much science at work, police departments and sheriff’s offices in urban areas are becoming increasingly savvy to how new technology can help solve crimes.
Examples of which can be seen in the use of crime scene reconstruction software and high-definition surveys to examine the accident and crime scenes. The best photogrammetry software provides height, area, and distance measurements of objects from a single scale measurement, whether or not the original camera source is available.

Traditionally, accidents and crime scene investigators use a camera and a notebook to record important physical data. But when the researchers to process the scene by making traditional 2D diagrams. They made a subjective decision on what to record and what should not.
While the accident scene evidence such as skid marks and crime scene evidence such as blood spatter would always be saved. Investigations continue, they sometimes reach a point where reasonable evidence failed noted in relation to the scene.
Photos required for MultiView Measure can be taken at any time as long as there are enough similar features present from the evidence image. This process increases measurement accuracy and allows measurements to cover larger crime scenes.
Besides giving a “snapshot” of the accident and crime scenes, measure any geometric attributes of the crime or accident scene captured in multiple images.
Some police departments choose to outsource their crime scene reconstruction software, while others choose to buy their own software. In both cases, it offers investigators the information that they need. Unlike older surveying methods used analogue and GPS technology, the high-definition survey can produce survey results in just one session of the survey, which is almost always the case with accidents and crime scenes.
