Belonging to courts of judicature or to public discussion and debate, is the common definition of forensic. Forensic photography as used by law enforcement agencies, the fire services and industrial security employs a variety of camera equipment as well as numerous types of photographic emulsions. Identification of persons, objects and activities, often under adverse lighting conditions, make use of photographic materials that originally and normally were intended for entirely different purposes. The liberal attitude of the courts in todays society makes the use of photography imperative. Special techniques using filters, modified developers and specific light sources allow photography to play an ever increasing role in law enforcement.
