Photography, with the help of photographic light-sensitive materials or photomatrix, by recording optical radiation, image creation and storage technology. In press cinematography, this term refers to the pictorial resolution of a film by a cinematographer. Photographs are also called final impressions of photographic images made medically, on photographic or plain paper, on a digital printer.

Camera art, which is one of the types of fine art, was created on the basis of photography technology. The first stable photographic image was created in 1822 by the Frenchman Joseph Niepce, but it has not survived.[1][2] According to the decision of the IX International Scientific Congress, the date of the invention of the technology is considered to be January 7, 1839, when François Aragon made a report on daguerreotype during the session of the French Academy of Sciences[3][4][5][6].

A person who takes pictures is called a photographer. Basically, he also carries out the stages of image creation, but the technical part of the work is carried out by the photo editor.

Srory of photography.

The invention of photography was made possible by the combination of several discoveries. Ancient Chinese philosopher Mo Tzu as early as B.C. In the 5th century, he described the effect of the obscura chamber[8]. Later, in the 4th and 5th centuries, the Greek mathematicians Aristotle and Euclid independently described a similar device. Artists began using the device as early as the Middle Ages to create perspective paintings, and among Renaissance painters, the obscura chamber was widely known as the “dark room.” In 1694, Wilhelm Homberg described photochemical reactions, when a substance changes color under the influence of light. He also drew attention to the photosensitivity of silver nitrate, discovered three centuries earlier.[9] The first person to prove that light, not heat, turns silver salt dark was the German physicist Johann Schulz. In 1725, while trying to prepare an illuminating substance, he accidentally mixed chalk with nitric acid, which contained a small amount of dissolved silver. Schulz noticed that when sunlight fell on the white mixture, it turned dark, while the mixture, protected from the sun’s rays, did not change at all. That experiment led to a series of observations, discoveries in chemistry, and discoveries that led to the invention of photography.
