History In 1725 AP Bestuzhev-Rumin (1693-1766), chemist and later an amateur politician and Johann Heinrich Schulze (1687-1744), physicist, professor at the University of Gaul in Germany found that under the influence of light iron salt solutions change color . In 1725, trying to make the luminous matter, he accidentally confused chalk acid, which contained little dissolved silver. Schultz pointed out that when sunlight is on the white mixture, then it became dark, while the mixture is protected from the sun, it is not changed. He then spent several experiments with letters and figures that are carved out of paper and put on a bottle of prepared solution - obtained photographic prints on silvered chalk. Professor Schultz has published the findings in 1727, but he had no idea and try to make the images found in this way permanent. He agitated the solution in the bottle, and the image vanished. This experiment, however, gave impetus to a series of observations, discoveries and inventions in chemistry, which are little more than a century later, led to the invention of photography. In 1818 Russian scientist, X. I. Grotgus continued to study and set the temperature effect on the absorption and emission of light. The first photo in the world, «view from the window», 1826

Types of photos Black and white photograph - historically the first type of photography. After the appearance of color, and then digital photography, black and white images retained their popularity. Often, color photos to black and white for an artistic effect. Color photograph appeared in the middle of the XIX century. The first sustained color photo was taken in 1861 by James Maxwell, the method of three-color image (color separation method). To produce a color image by this method were used three cameras mounted with color filters (red, green and blue). The resulting images allowed to reconstruct the projection (and later, in press) color image. Digital Photography - a relatively young but popular technology. The principle of operation of digital cameras is to fix the flux sensor and converting the information into digital form. Currently, digital photography everywhere replacing foil in most industries.

The main details of camera Camera has: •light-tight chamber that protects the photosensitive material from light exposure to outsiders during the shooting; •light-sensitive material (photographic plate, film) or electron-optical sensor with associated equipment; • lens with projection on the sensor; • Shutter (its role can perform the lens cap, in the simplest digital cameras, the shutter as a separate device may be absent, his functions are performed by electronics);

Tazio Sekkyaroli was born in 1925 in Rome and died on the 24 July 1998. He was a famous Italian photographer. Tazio Sekkyaroli was born in 1925 on one of the Roman borderlands. He became a photographer in 1944 taking photoes on Roman streets of American soldiers and tourists. In 1951 Tazio Sekkyaroli was acceped to the agency " Wedo " of Adolf Pastorelya , one of the fathers of Italian photojournalist who learned Tazio Sekkyaroli all the secrets of mastery photographer. In 1955 he founded the agency "Roma Press Photo" with Sergio Spinelli . Since 1958 he began cooperation with Fellini and after the movie "Sweet Life" stopped working at the"street photographer" to devote himself to studio photography. Sekkyaroli became personal photographer of Sophia Loren and remained so for over twenty years. He stopped taking photographs because photography requires all vitality. In 1983 Sekkyaroli decided to stop taking pictures . Sekkyaroli died in his sleep in his home in Rome the night from 23 to 24 July 1998. Sekkyaroli was a prototype of paparazzi from the Fellini film "La Dolce Vita." The name Paparazzi came from the name of the character of this film. Tazio Sekkyaroli
