Forensic science holds the branch of forensic photography which encompasses documenting both suspected and convicted criminals, and also the crime scenes, victims, and other evidence needed to make a conviction. Although photography was widely acknowledged as the most accurate way to depict and document people and objects, it was not until key developments in the late 19th century that it came to be widely accepted as a forensic means of identification.
Overview
Forensic photography resulted from the modernization of criminal justice systems and the power of photographic realism. During the nineteenth and twentieth centuries, these two developments were significant to both forensic photography and police work in general. They can be attributed to a desire for accuracy. First, government bureaucracies became more professionalized and thus collected much more data about their citizens. Then, criminal justice systems began incorporating science into the procedures of police and judiciaries. The main reason, however, for the acceptance of police photography, is a conventional one. Other than its growing popularity, the widespread notion of photography was the prominent belief in the realism of the medium.
History
The earliest evidence of photographic documentation of prison inmates dates back to 1843–44 in Belgium and 1851 in Denmark. This, however, was solely experimental and was yet to be ruled by technical or legal regulations. The shots ranged from mug shot resemblances, to prisoners in their cells; and the purpose of them also varied from documentation to experimentation. There was no training required and pictures were often taken by amateurs, commercial photographers, and even policemen or prison officials.
By the 1870s, the practice had spread to many countries, though limited to larger cities. Professional photographers would then be employed to take posed portraits of the criminals. This was early evidence that led to the standard mug shot known today and was unlike any previously known portraiture. Though there was no set standard yet, there was rarely creativity employed with lighting or angle. This was not like photographing portraits of families or children. These were documenting criminals. It was one of the first times people saw portraiture being used for something other than art. Though these were slowly adapted to police regulations, photographing criminals and suspects was widespread until the latter part of the 19th century, when the process of having one's picture taken and archived was limited to individuals convicted of serious offenses. This was, of course, by discretion of the police.
As the number of criminals climbed, so too did the number of photographs. Organizing and storing the archives became a problem. Collections called, "Rogues Galleries" classified criminals according to types of offenses. The earliest evidence of these galleries was found in Birmingham, England in the 1850s. Shortly after this were initial attempts at standardizing the photographs.
Alphonse Bertillon
French photographer, Alphonse Bertillon was the first to realize that photographs were futile for identification if they were not standardized by using the same lighting, scale and angles. He wanted to replace traditional photographic documentation of criminals with a system that would guarantee reliable identification. He suggested anthropological studies of profiles and full-face shots to identify criminals. He published La Photographie Judiciaire (1890), which contained rules for a scientifically exact form of identification photography. He stated that the subjects should be well lit, photographed full face and also in profile, with the ear visible. Bertillon maintained that the precepts of commercial portraits should be forgotten in this type of photography. By the turn of the century, both his measurement system and photographic rules had been accepted and introduced in almost all states. Thus, Bertillon is credited with the invention of the mug shot.
Some people believe that Bertillon's methods were influenced by crude Darwinian ideas and attempted to confirm assumptions that criminals were physically distinguishable from law-abiding citizens. It is speculated in the article, "Most Wanted Photography," that it is from this system that many of the stereotype looks (skin color, eye color, hair color, body type and more) of criminals in movies, books and comics were founded. Although the measurement system was soon replaced by fingerprinting, the method of standardized photographs survived.
