Technological age
Photography is regarded as the greatest invention of the 19th century. The way was long to today's photography. Over the centuries, the effects of light on light-sensitive substances were researched step by step, the methods for obtaining images through them were developed, and the camera obscura, the camera's predecessor, was perfected.
The camera obscura is a closed box with a small hole. When we hold an object in the lens, an inverted image of the object appears on the opposite wall. The famous Italian artist Leonardo da Vinci is regarded as the inventor of the camera obscura. The camera obscura is the forerunner of the modern camera. It is the most straightforward optical device that enables us to get an image on the screen. Camera obscura translates from Latin as "dark room".
The device's operating principle is as follows: Rays passing through the hole reach the screen or cardboard and show an inverted image of the object on the front of the device. The greater the distance between the hole and the screen, the larger the image. The quality of the image depends on the diameter of the hole. The smaller it is, the sharper and darker the image. It may become brighter as the diameter of the window is increased, but the image may become blurred. There have been various attempts to fix the image. One of the first photographic processes, developed in 1835 by the scientist William Henry Fox Talbot of Cambridge University, was the production of the first light-sensitive paper.
The camera shown in the photo is the oldest among the cameras kept in the photo salons of Batumi.
