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 19th 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

Therefore, the big cameras which were difficult to carry were no longer used. These cameras were sent to the factories after the photographs were taken. There, the gelatin film was left out of the paper and placed on the glass. Then it was sent back to the owner after it had been filled with a new film. That was the root of the amateur photography.

Today’s camera, SLRs (Single Lens Reflex), an able to form both image and focalization. With them, we can see the image on the screen and correct it on digital stage. The main form of the dark box is used in the today’s advanced cameras, too.

As it happens in every field, the camera has become so advanced keeping up with technology.
