The very first photo

The very first photo appeared in the 20s of the XIX century. The photograph was taken by Joseph Nicephorus Niepce (1765-1833), and it happened in Burgundy, France. At that time, methods of printing images (for example, lithography) were already known. However, the reliability of the reproduction depended on the skill of the artist: the artist painted the portrait, the engraving was made from the portrait, and the prints were printed from it. Niepce began to study various ways in which engravings could be reproduced. To do this, he used an old camera obscura - a light-tight box with a hole. The light rays passing through the hole created an image on the opposite wall, it was inverted. Niepce wanted to save this image, to "catch" it. At the place where the light painted the picture, he installed a plate, which he covered with a photosensitive compound. Under the influence of light, different parts of the plate darkened in different ways. After a while, the outlines of objects began to appear. So Niepce got the first photograph in history.

In his photograph, Niepce captured the landscape - a view from the window, with the roofs of neighboring houses. The exposure (exposure to light on the plate) lasted more than eight hours. During this time, the lighting changed almost cardinally, so that the picture turned out to be very unusual, and the view from the window itself is not entirely recognizable.
