This picture was taken in a photography studio and it was taken because the first thing that comes to my mind when it comes to investigation, is fingerprints. They are one of the main elements that are used for DNA profiling and matching of physical data which will eventually provide valuable information for an investigation. They are mostly used in criminal investigations and they often provide crucial pieces of evidence that can link a suspect to a crime. Prints are typically collected from a crime scene by specialists trained in forensic science techniques to reveal or extract fingerprints from surfaces and objects using chemical or physical methods. The fingerprint images can then be photographed, marked up for distinguishing features by latent fingerprint examiners, and used to search an automated fingerprint identification system.
