History of Photography
What we call the photograph appeared in its most primitive form in the 1820s. Then the first permanent photographs were taken. Of course, there have been many scientific advances that led to the invention of photography. Two silver compounds, which are both sensitive to light have been discovered by scientists, long before the first photograph was produced. Albertus Magnus discovered silver nitrate in the 13th century, and Georges Fabricius discovered silver chloride in the 16th century. In comparison, the silver nitrate is not sensitive to light, while silver nitrate is extremely sensitive to light. Silver chlorate is still used today to manufacture photographic paper because many react with photons, and gives a latent image, which is invisible until the development of the film via photoreduction.
1825 is the year the photograph was first invented. French Inventor Nicéphore Niépce it produced on a polished pewter plate covered with bitumen of Judea, which is just a derivative of petroleum. The image was taken with a primitive version of what we now call a camera, and took an exposure of eight hours in full sun to grow. Since the bitumen of Judea hardens when exposed to light, the surplus could be wiped off and the metal plate may be polished. This would create a negative impression, when covered with ink and pressed on paper, would create an impression. Niepce began his experience with silver compounds similar to those of research and discovered by Magnus and Fabricius, and based on his experience off the 1972 Johann Heinrich Schultz discovery as chalk and certain silver compounds, when they are combined, darken when exposed to light. Discover Schultz began the basis of all photography, even today.
Niepce then to form a partnership with Louis Daguerre, with whom he has perfected the current process of silver photoreduction. They worked together until 1833, when Niepce died of a heart attack, leaving his work to Daguerre. Daguerre, even though he had absolutely no scientific basis, has two enormous contributions to photography. It included two processes, which could combine to form a latent image of silver. First, before exposure to light, you must disclose the money to iodine vapor, then after exposure to light, you must expose the silver to mercury vapor. These two processes, when used together create a latent image. This process is almost exactly like the process used today with Polaroid pictures. He was introduced to the world January 7, 1839, daguerreotype, the French government immediately bought a patent, and made public domain. A very similar process has also been made in 1832 by the French-Brazilian painter and inventor, Hercules Florence, who called Photography. This is how modern photography takes its name.
In 1840, Fox Talbot greatly enhanced photography. Because of the potential danger of sodium thiosulfate is capable of dissolving the silver salts used in the process of photography, as noted by John Herschel, an astronomer, Talbot has changed the process to split the silver chloride on paper, which created a negative impression through. Originally, Talbot patented his invention of "photo paper", as it is called now, but he spent the rest of his life to defend its patent in court, and finally decided on this. George Eastman has proceeded to further refine Talbot, now what is used in most cameras today's chemical. Hippolyte Bayard also developed a method of photography but delayed announcing it, So, consequently, it receives no credit for the invention.
The daguerreotype has finally become very popular throughout the industrial revolution, as there was an increased tendency to have a portrait of himself. Oil paintings could not cope with the demand of time, and photographs began to become increasingly popular, until they were "the thing to have, so to speak. L 'photography business has not declined, but because of the fact that daguerreotypes were very fragile and very difficult to copy. This has been corrected in 1884, however, by George Eastman of Rochester, New York. Company Photography Eastman helped greatly by the establishment of dry gel on paper. Do not recognize this invention? Because we call the movies, and he gave photographers an easy way to do their work. Instead of lug around a bunch of metal plates and toxic chemicals, they need only carry a couple of rolls of film, and they can get more pictures out of it too. It is also simple and cost effective compared to developing printing plates of metal. The head of innovation at the Kodak camera, which Eastman was released in 1888. The slogan "You push the button, we do the rest." It certainly appealed to many people, and after the release of the Kodak Brownie in 1909, everyone and not just "professionals" took pictures.
Now, we had the latest innovations that make the consumer digital photography, but let us not forget how we got to this point, and all the hard work of many scientists set to give us the One of the most popular sport in the world.
