Why do CSIs collect evidence?
Because there is rarely more than one opportunity to obtain evidence from a crime scene, the investigation by the CSIs must be methodical and complete. In keeping with Locard’s exchange principle, CSIs collect evidence from the crime scene that may have been touched or microscopically “contaminated” by the suspect or suspects. They also take samples of fibres, dirt, and dust.
What is the forensic science?
That principle gave rise to the forensic sciences, which are the accumulated methods for developing and analyzing physical evidence from crime scenes.

What is forensic photography?
On the other side of the spectrum of forensic photography, is the crime photography that involves documenting the scene of the crime, rather than the criminal. Though this type of forensic photography was also created for the purpose of documenting, identifying and convicting, it allows more room for creative interpretation and variance of style.
Why is forensic photography important?
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.
When did mug shots start?
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.
Who invented the mug shot?
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.
Who was the first photographer to use the same lighting and scale for identification?
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.
When were photos taken in prison?
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.

There was no training required and pictures were often taken by amateurs, commercial photographers, and even policemen or prison officials.
When was the first case of forensic firearms?
The first case of forensic firearm examination to be documented was in 1835. That was when Henry Goddard applied ballistic fingerprinting to link a bullet recovered from the victim to the actual culprit. On careful inspection, he found that the bullet had a defect on its surface which did not seem to be from the barrel or the result of an impact. It seemed more like a defect acquired during its manufacturing. Anticipating that the shooter would have made the bullet himself, he realized that recovering the bullet mold would easily help him confirm the shooter. He was thus able to exactly zero in on the shooter when the mold found at the suspect’s home matched the marks on the bullet. This proved as a crucial evidence in convicting the shooter though he did also confess to the crime eventually.
Who created the Bureau of Forensic Ballistics?
In due course, Waite along with physicist John Fisher, Major Calvin Goddard, and chemist Philip Gravelle, established the Bureau of Forensic Ballistics in New York City. Philip Gravelle eventually developed the comparison microscope (two microscopes connected by an optical bridge) solving the challenges of simultaneous comparison.
What is forensic fingerprinting?
This meant that the bullets fired always bore some exclusive impressions which were unique to a specific firearm. Thus began the first instances of the careful examination of a bullet in order to trace it back to the gun used to fire it. And this laid the foundation of what is now called as forensic fingerprinting – the forensic examination of firearms and other evidence (bullets, cartridges etc.) recovered from the crime scene to link them to suspects or the specific weapons used in a crime.
How did forensic examiners match bullets?
Thus, whereas a forensic examiner could specifically match the rifling marks on a bullet recovered from the crime scene to those on the firearm’s barrel, it became increasingly difficult to match a bullet to a specific firearm made by a specific manufacturer through simple observation. And as they say, necessity is the mother of invention! So eventually, this paved the way for the magnified observation of bullets.
