Photography is the art of painting with light
With the passage of time photography has evolved steadily each day are more technological resources to improve their quality, but the picture would be today if the discovery of the XIX of this tendency I focused on artistic objectivity naturally imitate the reality.
Although considered to Nicephore Niépce the father of photography, note that to be the result of many attempts invention, in the field of physics and chemistry, tested at the same time in different countries, Fox Talbot and Hippolyte Bayard worth sharing that parenthood.
The pinhole camera:
The principle of the pinhole camera and mentions Aristotle and the Arabic optical Alhazan eleventh century. This principle was applied to observe solar eclipses.
Roger Bacon studied in 1267 and was accused of evoking the dead by the ecclesiastical court.
Around 1515 Leonardo Da Vinci provides a detailed description of the camera obscura:
“When images of illuminated objects penetrate through a hole in a dark room, you will receive these images inside the room … appear decreased in size. Be presented in an inverted position …”
In 1550, the Milanese Girolamo Cardano added to the chamber a glass disk. And Giambattista Della Porta his pupil mentions the use of the camera obscura to project images onto a white wall in order to get pictures.
Since ancient times it was known that silver salts darken under the action of light and the medieval alchemists called the chloride of silver “moon cornata”.
In 1727 the German Schulze discovered the property of black light, which has a mixture of chalk, etching and silver nitrate. But they often point to the Swedish Schelle (1747-1786) as the first systematic student of these chemical reactions.
French physicist Jacques-Alexandre-César Charles (1746-1823) gets the first silhouette on a paper impregnated with silver salts. In 1802 the Englishman Thomas Wedgwood improved the French experiment, but images can only be referred to the shade for a few minutes (they lacked a fixative).
In 1819 the astronomer John Herschel states that you can use the hyposulphite of soda as a fixer of silver salts, but can not think of applying to the experiments of Wedgwood.
It was in 1826 when Joseph finally gets Nicephore Niépce first chemical formula that will fix an image on a permanent basis.
“A new medium for setting the view that nature provides without having to resort to an artist”
Daguerre did not provide more than an alleged improvement of the camera obscura andpromised to improve the blueprint.
On July 3, 1833, in his study of Saint-Loup-de-Varennes, Niépce dies.
In the years 1835 and 1837 Daguerre made changes to the association, with the consent of Isidore (son of Joseph-Nicephore Niepce), and thereafter only the name of Daguerreand is called the daguerreotype process.
In 1838 Daguerre disclosed the invention, minimizing the role of Niépce.
Isidore Niépce in 1841 published the book “Historique de la découverte improprementnommée Daguerreotype”, which revealed the true facts. But when Daguerre died in 1851, the Society of Fine Arts gave him a grave-monument with the following inscription:”Daguerre, painter, chemist, inventor of photography”.
In 1867 Victor Fouque published clearly the facts of the discovery, restoring the truth.
The picture is the carrier of memories. As the newspaper Lumiere in the year of 1939:
As of today we can travel without moving
