Photographic Camera

The photographic chamber

This instrument was discovered by the great painter and inventor Leonardo da Vinci (1452 - 1519).  He made this discovery when he was hanging out in his dark room which was protecting him from the intensive summer sun.  He observed that on the wall there was an identical landscape to the outside one, only inverted.  This incident resulted in the birth of the idea of an obscure chamber that afterwards became known as the photographic camera.

In the beginning of the 16^th century the Arabic, Ibnol Haitham, studied solar and lunar eclipses.  He wanted to make the beams of light emmitted by the sun and reflected by the moon go through a small hole.  These were then projected onto the wall of a dark room. This principle was used later in the 17^th and 18^th centuries to draw constructions and landscapes.  In 1893 the French "Daguerre" employed the use of copper plates covered by an iodide of silver.  These materials (that printed the objects observed on the plates)  However, these materials were inconvenient to use because the photographs had to be prepared first, and then revealed immediately after they were exposed.

After some time, a new method was discovvered by George Eastman.  This method consisted of applying flexible celuloide onto sensitive plates with tape, so that negatives could be obtained and stored in rolls without being damaged. could damage.

In 1907 the scientist Lumiere introduced a new technique in the trade.  The first photographic cameras were developed to obtain photos in color.  But the first real color photograph appeared in 1935 when the companies, Kodak and Agfa, produced photographs by emulsion in three caps with all colors.

Elements of the Photographic camera

Objective : optical system consisting of several lenses.  It channels light that locates the objects before it is reflected.

Plugging: mechanical or electronic system that permits the transmision of light through the optical system during a given time.

Diaphragm: mechanical or electronic system that regulates the intensity of the light that it needs during the time it is open.

Approach system: moves the position from the objective, so that the entire image is formed on the sensative plate.

System for movement or the movie: system that allows a new movie to be placed before each take.

Visor: optical system that allows you to straddle the visual field that is being photographed.

Box: A sealed casing to hold everything in.
