The first photo in history known as "Boulevard du Temple", which was taken

by Louis Daguerre probably by the end of 1838 or early 1839.en image you could see it was a busy street, traffic was going to appear consecutively .. but a man is an exception in the left corner.

"Daguerreotype" was the first photographic process was officially announced and released in 1839. Robert Cornelius capture a portrait that is said to be the first image ever taken to light, this is the portrait of the first photo of a human being.

The Frenchman Joseph Nicephore Niepce captured the first permanent photograph (which was later accidentally destroyed) the intelligent use of what was dish was covered with a petroleum derivative called bitumen of Judea.

Niepce and Daguerre it were associated in the refining the existing silver process. Niepce died later leaving all his notes to Daguerre. Although he did not have good knowledges scientists made two major contributions, first discovered that silver was primarily iodine vapor before exposure to light later mercury vapor then taking the picture the image will be dormant. in 1839 announced that it had managed something with which silver is used in a daguerreotype called dish. The French government bought the idea for that outside dominated.

Fox Talbot read about the invention of Daguerre and is dedicated to perfecting the idea of Daguerre in 1839, thus achieving a key improvement, a effective fixative. The invention a process calotype . That sheets of paper coated with silver chloride to recreate an intermediate negative image. Unlike the daguerreotype, was he calotype poducir using as reference for positive copies .. like most chemical films of today, George Eastman talbot refining the process, which is the core technology used by chemical film cameras today.

John Herschel performed the first glass negative.

Janez Puhar invented a process for making photographs on glass, and was later recognized by the National Academy "Manufacturière et commerciale" in 1847.

Photographic experimentation in the nineteenth century it became very popular while the

In 1847, Count Sergei Levitsky Lvovich contribute something very interesting and was that improve much the focus of a camera ... transcending so the same design during years, thus even today are now. That man would be the first to introduce funds interchangeable decorative in the photographs, including also negatives to reduce or eliminate the technical deficiencies

The modern photographic process was born of a series of fixes and improvements in the first 20 years.

In the twentieth century, photography was an effective development with a commercial service users that who purchased the photographic equipment, and represented 20% of revenue to the industry.

The first photograph was digitally scanned occurred in 1957 and this process was invented by Russell A. Kirsch computer pioneer.
