The forensic photography is used as an evidence for the jury, as well as an aid for the forensics, due the fact there is evidence which was not considered in first place.
This kind of photography allows to detectives, policemen and military corpse in general to analyze crime scene once the homicide or suicide occurred, at what time it was reported, the place which took place, who was the victim (or victims) and the time when it supposedly happened, as well as access to the people who were staring outside the crime scene.
Forensic photography can be introduce as a proof which either leads to a question for the lawyer, as well as be taken as a proof for the jury to either make the responsible confess the murder or clarify the real situation which happened inside the crime scene.
Types of forensic photography
The type of camera which is used to crime scenes differs not only by design, also about what kind of effects should be proceeded once the pictures were taken, for instance, a standard camera has rolls by which have different techniques to be revealed, instead of a digital camera which do not need rolls for take the picture, even though has different techniques to processed information once the person in charge of the investigation wants to zoom the picture, here, some features about both cameras:
Standard camera: it is called a film camera as well because the film is the light sensitive by which the picture is taken. This light which passes the lens and redirected it in a form of a picture, by which has even more capture quality depending on the type of Len it is used to take it. There are many components of this camera, the most important are:
*Focusing mechanism: allows the photographer to make a close up of any particular part or place of the crime scene, as well as someone in particular.
*Shutter: protects and graduates the lent of too much light, and allows to take the picture when the crime scene is lighter per se.
*Lens: a curve glass which uses the light to capture the image.
*Viewfinder: allows to see the picture inside the camera in order to focus the picture.
*Aperture: is the hole that opens for light to travel
Digital camera: is the most advanced camera so far, it has an easy design to carry when you need to take a picture right away, the pictures are transferred immediately to PC and there is a LCD screen which allows the photographer to stored and view pictures inside the camera, correcting if there is mistakes and moving on.
Aids and flaws of forensic photography cameras
Most of the advantages of these cameras are related with the techniques used to reveal pictures, zoom in and zoom out, analyze crime scenes and detecting imperceptible evidence.
As a disadvantage, these cameras have difficulties based on the techniques how the information is processed: for standard cameras, rolls and other equipment needed is very expensive.
For digital cameras there is no exception: even though they are very fast and easy to process pictures, it does not have any hackers protection, which makes it very risky for the person who own them.
