Jacques Mande Daguerre

Photography! None other than Louis Jacques Mande Daguerre was the one who in the 1830s managed to find practical photography.
Daguerre was born in 1787 in the town in northern France Cormeilles. When young he was an artist. At the age mid-thirties, he designed a "diograma", line painting stunning scenery good, performed with the help of lighting effects.
While he worked on the job, he became interested in the development of a mechanism to automatically re-create the scene in the world without using kwas or paint. In other words: the camera!
The first level of design tools that can function the camera did not work. In 1827 she met Joseph Nicéphore Niépce who also is trying (and far more successfully) to create the camera. Two years later they became joint. In Niepce died in 1833, but Daguerre continued his experiments remain diligent. By the year 1837 he had succeeded in developing a practical system of photography which he called "daguerreotype."

Daguerre in 1839 open the public informed without mempatenkannya. In return, the French government presented a lifetime pension to both Daguerre and Niepce children. The announcement caused a stir Daguerre invention residents. Daguerre was a hero then, sprinkled with assorted respect, while the method of "daguerreotype" quickly evolved into something that is used by the public. Daguerre himself soon retire. He died in 1851 in his hometown near Paris.

Not many technological inventions so widely used as ordinary photography. He is used in almost every field of scientific investigation. So too in the field of industrial and military. Vital tool in the common people, hobbi fun for millions of people. Photography took part in the dissemination of information (or a fraud to deceive people through false information), in education, journalism and advertising. Because photography can quickly remind people of his past, he became a means souvenirs and mementos widespread. Cinematography, of course, is the next development that has significance apart from serving and is a means of entertainment that can not be ignored, Saina also used the equivalent of pictures of "silent."

There's no scientific discoveries made by a person alone without any help from previous people as Daguerre. "Camera obscura" (a tool similar to a camera but without the film) has found the eight centuries before Daguerre. In the 16th century, Girolamo Cardano make a lens placed in front of "camera obscura" open. This is an important step towards the birth of the modern camera. But because the image produced is not durable at all, it is difficult is considered a photographs. Another discovery was found year beginning in 1727 by Johann Schulze discovered that silver salts are sensitive to light. Although he used this discovery to create temporary images, Schulze had no idea how I should continue the idea.

Preceded close to what was successfully done Daguerre and Niepce who became a partner Daguerre. Around the year 1829 Niepce discovered that the thick black rock from Judea, a kind of asphalt, very sensitive to light. By combining the light sensitive objects with "camera obscura," Niepce made the first photograph in the world (one of which dijepretnya year 1826 still exists today). On that basis, some people think that Niepce was regarded as the inventor of decent photography. But photography Niepce system completely impractical because it requires no less than eight hours for the acquisition and it was only produces images Guram.

Official camera of diprodusir Daguerre in-law, Alphonse Girous, spiked with stamp which reads: "Without the signature of M. Daguerre and M. Giroux signs, not guaranteed." Because it has the practical meaning of excess.

Daguerre method, the image recorded on the sheet that covered "silver iodide". Taking the necessary time between 15-20 minutes is sufficient even take him because of severe nuisance, yet useful. Two years after Daguerre demonstrated his invention in public, people suggested improvements: the addition of "liquid silver" in the "silver iodide" light sensitive. These small changes have reduced the influence of time required for shooting, because it has the practical meaning of excess.

In 1839, after Daguerre announced the findings openly photography, William Henry Talbot, a British scientist, told also that he has developed other photographic methods, by printing a negative way, as do people today. Interesting to note, Talbot is already a portrait memprodusir tool in 1835, two years before Daguerre model solution. Talbot, who was also involved in various projects, not hastily continued photographic experiments. If this is done, maybe once she could photograph memprodusir commercial instrument before Daguerre did, and can be regarded as the inventor of photography.

The years after Daguerre and Talbot, people do different successive refinement: the process of wet sheets, dry sheets process, a modern film, color film, movies, Polaroid and xerography. Although many people are involved in the development of photography, I consider Louis Daguerre was the person who contributes most minds. There was no proper system in use before Daguerre and developed a system that most practical and most widely accepted. Moreover, extensive broadcasting of the invention is a driving force for further improvements. It is true, photography as we know now far different from Daguerre system, but even if such improvements are not anything there, yet what made Daguerre was able to be utilized. Michael H.
