History of Camera


The current model of camera is the result of a technical evolution that began about 200 years ago, which led almost all the cars to be equipped with a microcomputer.

Many are the dates which trace the birth of photography, but the first time it came to photography was in 350 BC, in "Problemata", Aristotle spoke of the light sensitivity of certain substances.

They have to spend another 400 years or so (70 dc) before Pliny the Elder writes: "quattuor coloribus solis immortalia ilia work ..." (only four colors immortalized this work).

And it is only in 1500 the AC Leonardo Da Vinci that describes in detail the principle of the camera obscura: this date painters begin to portray the landscapes thanks to this discovery.

With Galileo Galilei in 1609 is perfected telescopic view of the recovery in 1657 and Gaspar Schott, thanks to two "sliding boxes" that allowed the variation of the distance between the lens and the plane in which the image was created, manages to find the right adjustments focus of the "camera obscure".

Now it can be said that it began the camera.

They spend about two centuries before Nic├ępore Niepce in 1826, made use of the first device used to produce photographs constructing the original stable images in Black and White obtained using "bitumen of Judea" as sensitive material, laid out on a sheet of pewter.

The evolution of optics on the one hand and the construction technique on the other (for example due to the bellows) brought cameras to be more compact and transportable.

Improved techniques for developing and printing goes hand in hand with the inventions of the various policy: in 1859, thanks to Cooke, born the first "flash" with the use of magnesium.

In 1880 comes the first photographic film and eight years later in 1888 George Eastman Kodak devises the name for his first camera.

The twentieth century opened with another important step: in 1907 the brothers Lumiere debug process for the development of color film. Throughout this century we will walk important in improving the camera and in experimenting with new materials development and printing.

In 1913 Oscar Barnak, head of a department of a German optical company, built the first prototype of the Leica, in 1935 the Cnopm (USSR) patented the first SLR to 35mm film. In 1948 Edwin Land invented the Polaroid.

In 1959 the Nippon Kogaku produces the Nikon F and, the following year, the Konica F is the first SLR with plane shutter metal reaching shutter speeds faster than 1/2000 second.

In 1981, Sony introduces the Mavica, the first camera that uses a magnetic media instead of film, and the same year the Pentax opens the season of autofocus SLR.

1999 marks the digital age with the birth of the Nikon D1 SLR.

The current market offers a great variety of digital cameras arriving at resolutions up to 5 million pixels
