The portable darkroom with additional lenses developed in the 17th century. Permanent image of photograph, as we call it, was invented by Joseph Nicephore Niepce, a French physicist, in 1825. Before that, he became the first negative role in 1816. Niépce used a camera obscura to record the image on a polished pewter plate, coated with asphalt (a petroleum derivative). This was the first image retained for a longer period. Later, the experiment of Niépce, in collaboration with Louis Daguerre, French painter, led to the development of the daguerreotype plates to create permanent images. The basic principle is used in the daguerreotype was a picture taken on a copper plate coated with silver was exposed twice - first to iodine vapor, then followed by exposure to light.

Daguerre also discovered the phenomenon of latent image building as well as the picture exposure to mercury vapors. In 1839, he announced the invention of the daguerreotype to the public. Daguerreotypes were popular until the end of 1850, before the invention of the emulsion plates.

Put them together, which means "to bring to light." The term stuck, and has become a permanent part of our vocabulary. According to historians, the basic technology of photography has been around for a long time. The first photograph ever taken was conducted in 1827 by Joseph Niepce, a French inventor. The procedure took eight hours to complete a picture!

Before he died, years later, Sir Joseph Herschel was able to associate with Louis Daguerre, who was in Paris. Louis was experimenting with different methods of photography. In 1833, Sir Joseph died of a heart attack, leaving all the experiment documentation, as well as the technology of Louis Daguerre. Louis continued the hard work necessary to improve the technology of Daguerre had created.

In 1829, Louis Daguerre, a French artist and chemist, began working with Joseph Niepce to develop a better photographic process. In general, won the physautotype, working until Niepce's death in 1833. Daguerre continued his work alone and in 1839, Louis Daguerre announced his perfection of the daguerreotype camera. It uses a copper plate sensitized slide to record and sat on a wooden tripod. The latter model reduces the exposure time of approximately 30 minutes instead of hours and, fortunately, there was no confusion of the image as a model. The daguerreotype was the first commercially viable process for making portraits and almost gave birth to the "professional photographer".

Louis Daguerre was able to reduce the exposure time of 30 minutes. As he continued on improving the technology, which was accompanied by the son of Niepce who documented all the manual process called daguerreotype and sold to the French government. The method became very popular and eventually found his way to New York City.

Although successful, the daguerreotype had limitations. One was that it was a bit expensive and it was not possible to create duplicates. So somewhere along the lines of history, the calotype was introduced and has proved a tough competitor. William Henry Fox was the inventor of the calotype. He is also the inventor responsible for producing the first negative result in 1835. His method has continued to improve in quality. This is the story of Louis Daguerre, the inventor of photography.
