The Best Photo in the World
⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️
The history of photography began with the discovery of two critical principles: the first was the projection of an image using a camera obscura, and the second was the discovery that certain materials visibly changed when exposed to light. There are no artifacts or descriptions suggesting any attempts to capture images using light-sensitive materials before the 18th century.
View from the Window at Le Gras (1826 or 1827) is believed to be the oldest surviving camera photograph. [1] Enhanced redirection shown in original (left) and colorized (right).
Around 1717, Johann Heinrich Schulze used light-sensitive clay to capture images of letters cut out and placed on a bottle. However, he did not attempt to make these images permanent. Around 1800, Thomas Wedgwood made the first reliably documented attempt, although it was ultimately unsuccessful in creating permanent camera images. His experiments produced detailed images, but neither Wedgwood nor his assistant, Humphry Davy, could find a way to fix them permanently.
In 1826, Nicéphore Niépce was the first to successfully fix a camera image, although the process required at least eight hours—or even several days—of exposure, and the results were extremely crude. Niépce’s assistant, Louis Daguerre, went on to develop the daguerreotype process, the first publicly announced and commercially viable photographic technique. The daguerreotype only required a few minutes of camera exposure and produced sharp, detailed results.
On August 2, 1839, Daguerre presented the details of the process to the Chamber of Peers in Paris. On August 19, the technical details were published at a joint meeting of the Academy of Sciences and the Academy of Fine Arts at the Institute Palace. (In order to make the invention public, Daguerre and Niépce were granted a generous lifetime pension.) [3][4][5] When the daguerreotype process was officially unveiled, it marked the beginning of modern photography.
