Crime scene photography, or forensic photography, is a field of photography that deals with photographing crime scenes, corpses and evidences, according to ExploreForensics. The photos are documented for use in investigations.
Crime scene photographers are always allowed to enter the crime scene from the beginning in order to take detailed and accurate images, explains ExploreForensics. The photographers also document tagging and removal of evidence at the crime scene.
Crime scene photographs are used by both prosecutors and defendants as evidence in criminal cases, notes ExploreForensics. The photographs also help in recreating the crime scene, allowing investigators to make a detailed timeline of events. All crime scene photographs are time- and date-stamped.
