INTRODUCTION
Photo in the internal affairs bodies prominently and widely used as a means of fixing the evidentiary information in the course of the investigation. Photographic images allow to perceive the objects captured in the object space form and to a greater extent than it allows them a verbal description of the protocol of investigative action.
The study involves the examination of forensic photography not only its special species, but the general picture, because without the basic knowledge of the overall picture is difficult to master the techniques of forensic.
In 1989, 150 years old, was discovered photography. From the first years of its existence, it has received the application, not only at home, but also used in the decision purely scientific tasks. Photo (photo light, graph-write).
The appearance of pictures preceded by the opening of many scientists. The first camera (camera obscura) was a light-tight box with a hole in the wall, the principle of which is described in his writings still outstanding Italian scholar and Renaissance artist Leonardo da Vinci. Great contribution to the development of photography made Frenchmen Joseph Nicephore Niepce, Louis-Jacques Mande Daguerre and the Englishman William Henry Fox Talbolt. Daguerre, who worked until 1883, together with Niepce, received image on a silver plate, treated with mercury vapor and fixed with a solution of common salt. His method he called Daguerreotype. In his works, Daguerre used the study materials Niepce, but he never even mentioned. Technology Daguerre did not allow pictures to propagate and only Englishman Talbolta invention marked the beginning of the development of negative-positive method of obtaining photographs and contributed to the discovery of a new method for preparing a light-sensitive paper. In 1835 Talbolt soaked silver chloride paper, got her picture window of his house in the form of negativity. Then, enclosing a paper treated with the same solution, he received a positive mark. The pictures were far from perfect, but his invention proved the possibility of replicating Talbolt prints.
