Photography

The history of photography began in the early nineteenth century, when in 1816 the french scientistNicéphore Niepce got the first photographic images, although the oldest preserved photograph is an image obtained in 1826 with the use of a obscure camera and support sensitized using a chemical emulsion of silver salts. Niepce began their investigations, requiring eight hours of exposure to daylight to get your images. In 1839 Louis Daguerre made public process for obtaining photographs based on silver denominate daguerreotip, which solved some technical problems in the initial procedure Niepce and reduced exposure time required its procedure is the predecessor of the current snapshot of Polaroid. Almost simultaneously Hercules Florence, Hippolythe and William Bayard Fox Talbot developed various other methods. The created by William Fox Talbot was based on a paper covered ambclorur silver is much closer to the picture today, since it produces a negative image that would later be positive many times as you wish. By this time the daguerreotype was very popular, as it was particularly useful for portraits, custom common among middle-class. It is a fact that due to the huge demand for these pictures, much cheaper than painted, the picture was boosted enormously.
