A mug shot or mugshot (an informal term for police photograph or booking photograph) is a photographic portrait of a person from the shoulders up, typically taken after a person is placed under arrest.[1][2] The primary purpose of the mug shot is to allow law enforcement to have a photographic record of an arrested individual to allow for identification by victims, the public and investigators. However, in the United States, entrepreneurs have recently begun to monetize these public records via the mug shot publishing industry.
Photographing of criminals began in the 1840s only a few years after the invention of photography, but it was not until 1888 that French police officer Alphonse Bertillon standardized the process.
