La historia de la
It began with the discovery of two fundamental principles:
The first is the projection of images with dark camera, the second is the discovery that some substances are visibly altered with exposure to light. There are no artifacts or descriptions that indicate any attempt to capture images with light-sensitive materials before the 18th century.

Around 1717, Johann Heinrich Schulze used a light-sensitive suspension to capture images of cut letters in a bottle. However, he didn't try to make these results permanent. Around 1800, Thomas Wedgwood made the first reliably, albeit unsuccessful, documented attempt to capture permanent camera images. Their experiments resulted in detailed photographs, but Wedgwood and his partner Humphry Davy couldn't find a way to fix these images. In 1826, Nicéphore Niépce was the first to fix an image captured with a camera, but it took at least eight hours or even several days of exposure to the camera and the first results were very rudimental. Niépce's collaborator, Louis Daguerre, developed the Daguerotype process, the first commercially viable and publicly announced photographic process. The daguerrotype required only a few minutes of exposure in the camera and produced clear results with great detail. On August 2, 1839, Daguerre demonstrated the details of the process at the Chamber of Lords in Paris. On August 19, technical details were made public at a meeting of the Academy of Sciences and the Academy of Fine Arts at the Institute Palace. (For granting the rights of inventions to the public, Daguerre and Niépce received generous annuity for life. When the metal-based daguerotype process was formally demonstrated to the public, the competing approach to the paper-based negative daguerotype and salt-printing processes invented by William Henry Fox Talbot had already been demonstrated in London (but with less publicity). Later innovations made photography easier and more versatile. The new materials reduced the exposure time required of the camera from minutes to seconds, and eventually to a small fraction of a second; the new photographic media was more economical, sensitive or convenient. Since the 1850s, the collodion process with its glass-based photographic plates combined the high quality of the daguerotype with the multiple known printing options of the calotype and was commonly used for decades. Rolling movies popularized casual use by fans. In the mid-20th century, advances made it possible for amateurs to take natural color and white photographs and black The commercial introduction of computer-based electronic digital cameras in the 1990s quickly revolutionized photography. During the first decade of the 21st century, traditional film-based photochemical methods were increasingly marginalized as the vast practical advantages of new technology were appreciated and the image quality of moderately priced digital cameras were continually improved. Especially since cameras became a standard feature of smartphones, taking photographs (and posting them instantly online) has become an ubiquitous everyday practice worldwide 10/02/2019 Image 3
