History/Explanation of the technique
Forensic photography is the technique of photographing details within many different crime scenes, such as burglary cases, where fingerprints and any signs of forced entry would be gathered, or in murder cases where blood stains/spatter, hair and fibers would also be collected. This type of photography is essential within a police department's line of work, as the photographer documents pieces of evidence throughout the scene, which then are used within a courtroom as unbiased evidence, providing accurate images as a photographic record of the crimes committed. Also, there are other uses such as to jolt people’s memory if they happened to see something. The history of forensic photography can be traced back to the 19th century, where in the early day criminals had “mugshots” taken, this began in Belgium in the 1840s, where amateur photographers were employed.
The typical camera kit required to achieve forensic imagery should include the following: a professional-grade DSLR camera( without hot mirror), at least several memory cards, macro lenses, tripod with ball-head attachment, wide-angle lens, flash and cables, shutter release cable, many filters such as UV, IR transmission, hot mirror filter, also include extra batteries as cameras have been well known to die out without prior notice. Markers such as tape measures may also be used to take precise sizes from evidence, ensuring accuracy.
Techniques and explanation of the use

Infrared photography may be required to document such items of evidence as fingerprints and bodily fluids, and UV photography may also be required for bitemarks on bodies.
The applied technique of forensic photography is used in many everyday situations within a police department, from the scene of the crime collecting all different types of evidence to taking criminals' headshots.

Issues regarding the use of digital photography in police work
One of the issues regarding the use of digital photography in police work is that the photographs were manipulated or tampered with to draw conclusions from the people who see them.
