Camera

A camera is a device that records images, either as a still photograph or as moving images known as videos or movies. We choose this invention because thanks to it, we have the possibility of record a moment and make it last forever.




HISTORY:

The first permanent photograph was made in 1826 by Joseph Nicéphore Niépce using a sliding wooden box camera made by Charles and Vincent Chevalier in Paris. However, while this was the birth of photography, the camera itself can be traced back much further, in 1604 by the Johannes Kepler. Before the invention of photography, there was no way to preserve the images produced by these cameras apart from manually tracing them.
To take a picture, it took a long time of posing, but the development of the collodion wet plate process by Frederick Scott Archer in 1850 reduced it dramatically, but required photographers to prepare and develop their glass plates on the spot, usually in a mobile darkroom. Wet plate cameras were little different from previous designs, though there were some models, where the sensitizing and developing of the plates could be carried out inside the camera itself rather than in a separate darkroom. Other cameras were fitted with multiple lenses for making cartes de visite. It was during the wet plate era that the use of bellows for focusing became widespread.
The first colour photograph was made, in 1861, by Scottish physicist James Clerk Maxwell, with the help of English inventor and photographer Thomas Sutton.
The electronic video camera tube was invented in the 1920s, starting a line of development that eventually resulted in digital cameras, which largely supplanted film cameras after the turn of the 21st century.


CURIOSITIES:

- The forerunner to the camera was the camera obscura.

- The first camera that was small and portable enough for practical use was built by Johann Zahn in 1685, almost 150 years before chemical technology caught up to the point where photography was practical.

- The first permanent photograph was made in 1826.

- One snap-shot with the first camera in history would take eight hours of posing, no shaking.

- The first colour photograph was made in 1861.

- Photography had influenced modern art.

- George Eastman, the inventor of Kodak cameras, hated to be photographed.
