The discovery of image stabilization The first image took 8 hours to produce. In the last issue, we talked about the process of discovering photography in its first primitive stages, then about the first camera that Leonardo da Vinci named. Epscura camera. But even then, scientists had not reached an optimal discovery to stabilize this discovery and generalize it in the form of an image that lasts, and in this episode we present the research that led to the discovery of image stabilization factors, and when this was done on the morning of one of the painters in the last century, the era of photography began and the era of painting died. 1- The second episode - when he discovered the fixation of the image, one of the painters shouted: The era of photography has begun and the era of painting has died

The year 1727 was conducted by Johann Schultz, a German professor of chemistry. Numerous experiments to prepare phosphorus, and for that he emptied the slurry of lime over an amount of nitric acid, and he was amazed when he noticed that the content of the pot blackened after leaving it in front of the light, discovering traces of silver salts in this solution, but he did not pay any attention as he did not find No practical application for it After that, other enthusiasts clung to this discovery and worked on its application and development, among them Jean Halot, who inserted nitrate paper into it. It is very sensitive, as it blackens when exposed to light or sunlight. 1737 Ammonia solution after zero dissolves. This puts us in front of many things that enter the scope of the imaging process and image stabilization. As the light plays a key role in transmitting the specific radiations of the illuminated objects into the camera

In order for the imaging process to be completed, as we mentioned in the previous episode, if these specific radiations fall on a sheet of paper wet with the discovered silver solution, it will tend to blacken according to the varying strength and weakness of the light of the radiations, thus forming, without a doubt, the image of illuminated objects. Photography Therefore, we can attribute the word - which means writing with light - to Jean Halot because his research was related to secret writing, and this was done on paper and with a silver solution, as it remained invisible as long as it was not exposed to direct light. The production of the first image took 8 hours. As for the process of discovering photography, it goes back To the Frenchman Joseph Nicephore Niepce, but he fell into the same dilemma that faced his predecessor Josiah and Daoud R. He used the black arafa as the English craftsman, as the latter was meticulously drawing the shapes in which he showed his pottery groups. Then his name came Thomas, who learned the way of his father, Laura and Alddo, very dependent Here we are accustomed to being good with chemicals and the effect of heat and light on these materials, so he was the first - sensitive products in victory. These artefacts from the black band to the light, he needed a frozen material for the image or applied the idea of ​​photography Proven by memorizing it, and the Frenchman, Joseph Ness, with the help of his brother Kholoud, tackled this complex problem with new materials under test, until he discovered that one of them disperses the parts exposed to light and scares the other parts, so he called it the liter fixer, that is, we fix the parts of the image by means of this, so that we do not destroy the solution so that in the year 1827 Niepce reached the production of the first image in the world, as it took eight hours to obtain it, and after almost ten years, another Frenchman named Louis Dagber came to fix the image with table salt, and Dagbert, Dr. The project Dagber achieved great success with his new discovery, which he later called the Dagrootibe. and, dagrotype. It is a positive image, but it was not possible to re-obtain an additional copy, as it was rapidly perishable. Da Gbeir experienced great financial difficulties, which forced him to seek financial assistance from one of his influential friends, Francois Arago, a well-known physicist and astronomer, who initiated his assistance with the request To the French government to provide assistance to this discoverer to complete his new project, and what he wanted was done for him, and since then the picture became an established reality, and the mornings of the old painters came, so that one of them, called Paul de La Roche, announced that he had begun the era of painting and the era of drawing had died. . After standing on the details of Daghier's discovery
