Photography is a mixture of science and technology. It
involves clicking of an image on to a film to be reproduced and stored for
future use. In current times in addition to traditional photographs there is
influx of digital imaging where in place of film the picture is stored in a
digital way.
Use of these photographic techniques in forensic
investigations is known as forensic photography. In forensic field it is useful
at crime scene as well as in mortuary. Photography can help in storing of image
and its reproduction at a later stage and can play a valuable role in
investigation as well as in evidence in court of law. It includes pictures of
crime scene, victim, accused, weapons, evidence, vehicles (as in road traffic
accident) etc. A good photograph depends on quality of camera, illumination,
nature of object, angle of photography as well as expertise of photographer.
As the old saying goes “A good photograph isworth a thousand words”, a carefully clicked picture can go a long way in crime
investigation. To be fit for court the photographs needs to be clear, properly
scaled, clicked from multiple angles and deposited by maintaining chain of
custody. These pictures can either be overall images of the scene, context
images showing relation between relevant evidence (like dead body and murder
weapon), or close up images showing the details of evidence. As a general rule
color photographs are better than black and white as they can give a much clear
idea about the crime.
