Photography is the art of creating fine art photography. Image, reflecting the creative vision of the photographer as an artist.
In order to understand the essence of the art, we must first look at history and see the photos.
Using this device, people have tried to reproduce on paper what they see with their eyes. The principle is simple: it is a lightproof box with a hole and screen (frosted glass or thin white paper) on the opposite wall. The light beam passes through the hole and creates an inverted image that you can later use.
The development of the technology has not kept itself waiting, and already in the 17th century people used a mirror set at an angle of 45 degrees to the lens that reflects the image at the top of the box which you can install the tracing or paper.
In the early 17th century defined the physical laws of reflection mirrors, then invented a complex telescope. A little later, Johannes Kepler developed a theory of lenses, which have become a reliable scientific instruments. Was manifested a deep interest in this technology, and people slowly began to explore new ways. Artists, like scientists, were under the strong influence of these scientific researches.
But the photograph, the people came only after the discovery of the light sensitivity of materials. Chemical and physical properties of some substances marked the beginning of photography.
So it happened with Professor Gallic University (Germany). He accidentally mixed the chalk and nitric acid, which contained little dissolved silver. In the end, he noticed that when exposed to sunlight, the mixture darkens. After lengthy experiments with gluing the letters and numbers on pre-prepared bottles containing the solution, received a photographic print on paterbriana the chalk.
Already in the 19th century people learned to produce the first fixed image. It happened with the help of a pinhole camera on a tin plate, covered with a layer of asphalt. The exhibition lasted about 8-9 hours in bright sunlight. This experiment can safely be considered the beginning of photography.
There are several types of imaging:
There are also photographs, which preserves the altered state after different treatments. These include:
the photographic plate;
And only in the early 20th century, people learned to convert the analog picture to digital format.
In 1908 Alan Archibald Campbell Swinton (Scotland) publishes in the journal article, which describes an electronic device for recording images on a cathode-ray tube. In the future, this technology formed the basis for television. Cathode ray tube (CRT) converts electrical signals into light.
