Respected visitors let us introduce you the history of photograph and give you short review of photograph development since the beginning until the newest technological achievements. Inform yourselves about the projects of great inventors to whom we are very grateful because the world of photograph would not exist without their persistence. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Since the prehistoric times human beings have been watching and trying to note the world around them. Silhouettes reflected on the walls of the caves where they lived, reflections of their faces on the water surface…It was clear to them that images could have been transferred on the smooth surface but the question was how? Untouched nature that surrounded them offered a great number of examples that were unclear to them.
Photograph that is familiar to us today passed long way through the history. Its beginning was in the 16th century when by beliefs a great number of Rene sans artists used camera obscure. Guardi and Cannaleto used this device for making their pictures. It was as big as a little house and not heavy so two men could carry it. It worked on a simple principle: light was entering through a small hole in the wall and transferring an image on the walls of the box then painters transferred it on the canvas using different techniques. It was clear that already in the 16th century appeared ideas that helped in development of photograph. This idea was spread very fast among artists. As the results were astonishing artists started changing the construction, later on they started painting profiles using camera obscure. Painters improved camera obscure but nobody tried to stabilize an image. But why would they? Painters were earning enough for good living by making portraits; they just made the work easier.
1727. Professor of anatomy Johann Schulz performed several experiments in his laboratory and found out that some chemicals changed after having been exposed to light. He knew this was important but did not know how to use it.
Few years later a couple of scientists, who had known about this earlier conducted experiments, carried out several new experiments and earned their places in the historical development of photography. Namely, about 50 years later Carl Scheele found out that silver chloride particularly reacted to violet rays of spectrum. And of course few more inventions and scientific experiments led to the first photograph. After the discovery that some substances could be affected by light and clear notion about camera obscure, which could bring light on the place you wanted, scientists did not stop trying to find stabile chemical substance which would show the fixed picture truthfully.
