Today we speak of a very special piece you just become part of our collection: the camera obscura Chevalier. Let's start first to clarify what exactly is a camera obscura: the term derives from the word camera camera, which in Latin means"" room"" or"" camera"" . Johannes Kepler coined the name"" dark chamber"" for the first time in his treatise of 1604, defining the concept of this instrument, which will also be the basis of his invention of the telescope (although the concept of camera obscura was already known from the tenth century , in which the Arab Alhazen applied scientific principles to explain the formation of the visual image). The original camera obscura was nothing more than a darkened room whose only light came from a tiny hole in one wall. The light through the hole projected an image of the outside on the opposite wall, although it was inverted and blurry artists did not hesitate to make use of darkrooms for his sketches more accurately. With the course of the centuries that first room was evolving and improving, into a small manageable box and with an optical lens into the hole to get a clearer picture. In the nineteenth century it became widespread construction of such elements, helping unequivocally to the invention of photography largely thanks to Chevalier. This family of optical formed by grandfather (Louis Vincent Chevalier (1743-1800)), father (Vincent Jacques Louis Chevalier (1770-1841)) and grandson (Charles Louis Chevalier (1804-1859)) marketed its objectives through microscope his shop in the Quai de l'Horloge 69, which became suppliers of Niépce, who besides buying lenses for their cameras experimental sent them photographic evidence of their progress. Another customer of Chevalier was Daguerre, who as you know was also conducting its own photographic experiments, in fact look like a 1824 day he burst into the tent of the Chevalier exclaiming: I've found a way to fix the images of the camera obscura! I've caught the fleeting light and have chained! I've forced the Sun to paint my pictures! As you know the race to the invention of photography was not exempt from multiple trials and errors and years later the own Charles Chevalier wrote in his memoirs that"" Daguerre had claimed victory ahead of time"" (the daguerreotype was not officially announced until 1839 ). Finally Joseph Niépce was the first photographer in history, for whom the Chevalier invented and built the first camera in 1826. The Chevalier spoke to Daguerre and Niépce heliographs and thanks to his mediation painter and entrepreneur Daguerre could contact Niépce. Both perfected the camera obscura adding fasteners image in the plane of the screen and signed in 1829 a contract of incorporation through which Niépce, who died in 1833, revealed its progress in the development and commercialization of the invention . From this knowledge Daguerre finally able to announce and spread and in 1839 his famous daguerreotype.

Let us first clarify what a camera obscura exactly : the term camera comes from the word camera, which in Latin means" room" or" camera" . Johannes Kepler coined the name" dark chamber" for the first time in his treatise of 1604, defining the concept of this instrument, which will also be the basis of his invention of the telescope (although the concept of camera obscura was already known from the tenth century in which the scientific Arab Alhazen applied its principles to explain the formation of the visual image). Original camera obscura was nothing more than a darkened room whose only light came from a hole miniscule one of its walls . The light through the hole projected an image of the outside on the opposite wall, although it was inverted and blurry artists did not hesitate to make use of darkrooms for his sketches more accurately. With the course of the centuries that first room was evolving and improving, into a small manageable box and with an optical lens into the hole to get a clearer picture
in the nineteenth century the building became general of such elements, helping unambiguously to the invention of photography in large part thanks to Chevalier . this family of optical formed by grandfather ( Louis Vincent Chevalier (1743-1800)), father (Vincent Jacques Louis Chevalier (1770-1841)) and grandson (Charles Louis Chevalier (1804-1859)) marketed its microscope objectives through its store on the Quai de l ' horloge 69, where they became providers Niépce , who besides buying lenses for their experimental cameras sent them photographic evidence of their progress. Another customer of Chevalier was Daguerre , who as you know was also conducting its own photographic experiments, in fact look like a day he barged 1824 or store the Chevalier exclaiming:
I found a way to fix the images of the camera obscura!
I've caught the fleeting light and have chained!
I've forced the Sun to paint my pictures!
As you know the race to the invention of photography not been exempt from multiple trials and errors and years later the own Charles Chevalier wrote in his memoirs that" Daguerre had claimed victory ahead of time" (the daguerreotype was not officially announced until 1839). was finally Joseph Niépce the first photographer in history, for whom the Chevalier invented and built the first camera in 1826 .
the Chevalier spoke to Daguerre to Niépce and heliographs and thanks to mediation by the painter and entrepreneur Daguerre could contact Niépce. Both perfected the camera obscura adding fasteners image in the plane of the screen and signed in 1829 a contract of incorporation through which Niépce, who died in 1833, revealed its progress in the development and commercialization of the invention. from this knowledge eventually Daguerre was able to announce and spread and in 1839 his famous daguerreotype.
