Was the first description mapa zagreba of something like a camera Alhaken written by an Arab, in Basra, mapa zagreba who lived about 1000 years. He discovered how images are formed inside his tent when the sunlight passing through the slats of fabric. So were reported principles of what would the camera.
Cameras meant little room. Later, the camera nigra, when there was a picture, it was a ruse works realized images projected from the outside and whose silhouette was drawn in the darkroom. Its existence has been known since the sixteenth mapa zagreba century, when artists such as Leonardo Da Vinci and other painters used to draw. In the seventeenth century, the cameras are not dark and became mobile, detachable and semiportáteis. Drawing mapa zagreba with light, does this actually was usefulness of these things, so the etymological meaning of these words are Greek: photo (light) and grafein (draw). French brothers Jean and Claude Niepce Nikephoros are the first to relate the image taken with a camera light and darkness. But they did not only researchers in this activity, although these were coming mapa zagreba to the end of this practice. After this French artist Louis Jacques Daguerre's Request (1789 - 1851) worked for years to get a system where the light was shining on a suspension of single agent, so it was dark and they could produce selectively retained patterns in some scenes. In 1839, Daguerre learned dissolved salts intact in a solution of sodium tissulfato that allowed for ever saved image. There was even advance was remarkable, it took 25 to 30 minutes to take a picture, and if there was sun. But this was not its main disadvantage, but the difficulty of obtaining a copy. It was another inventor, William Henry Talbot (1800 - 1877), who was experimenting with what he called calotypes, which overcome the problem in 1841. With its calotypes get negative results that would be passed immediately to positive in other sheets. In 1844, was the first book published photographs. Since then, the investigation has focused on achieving a negative role for it to be sensitive enough to be printed quickly. In 1848, an English language sculptor, Frederick Scott Archer invented kolodyon wet process. Kolodyon mapa zagreba (composed of equal parts of ether and a solution made with alcohol and cellulose nitrate) was working as binder material to conform nitrate of silver mapa zagreba gives the plate glass fotosansibilite which formed the basis of the negative. Exhibition was designed and humid negative (this is the origin of the name kolodyon wet). This release had to be done immediately after taking the picture. Only after a few scientific breakthroughs were color photos. Gabriel mapa zagreba Lippman was the first investigator through a complex could photograph the visible spectrum and all its chromatic richness. Fees light also contribute, but were Louis Ducos du Hauron Charles Cross and those who have created a method that occurs in three negative impression mapa zagreba of filters with shades of red and blue.
