The first picture is a foggy image taken through the windows of the studying room of Nicephore Niepce, who had started to look for a way to fix the sights in the early 19^th century.

The first camera to be on the market was one called daguerreotype. It was improved by Louis Daguerre who had cooperated with Nicephore Niepce and was able to fix the sights. A cupric plate, which contained a little amount of silver, was placed into the machine after undergoing several chemical processes. The length of the time to pose varied from 5 min to 40 min, according to the circumstances of the light. It was not until the plate was placed into a 47,50 °C container, in which there was a little quicksilver, that an image appeared.

The English genius Henry Fox Talbot dived this plate in different chemical substances and managed to create a paper sensitive to heat. But the negatives obtained from these papers were not good enough and got dark before long. Sir John Harschel was the first to call Talbot’s works photograph. After some time, he also managed to turn the negatives into positive. In 1840, professor Joseph Petzual used an objective lens that transmitted the light sixteen times stronger and made the pose time shorter.

The machines that contained gelatin rolls covered with bromine were available on the market in 1852
