The history of
began with the discovery of two critical principles: the first is the projection of the dark camera image, the second is the discovery that certain substances are visibly altered by exposure to light[2]. There are no artifacts or descriptions indicating an attempt to capture images with light-sensitive materials prior to the shooting.

Around 1717, Johann Heinrich Schulze used a light-sensitive edge to capture images of letters cut onto a bottle. However, he has not pursued these permanent results. Around 1800, Thomas Wedgwood made the first reliable attempt at capturing camera images in permanent form. His experiments resulted in detailed photographs, but Wedgwood and his associate Humphry Davy found no way to fix those images.
In 1826, Nicephore Niépce first succeeded in repairing an image that had been captured with a camera, but at least eight hours or several days of exposure in the camera were necessary and the initial results were very rough. Niépce's partner Louis Daguerre continued the development of the daguerreotype process, the first publicly and commercially viable photographic process. The daguerreotype required only minutes of exposure in the camera and produced clear and finely detailed results. On August 2, 1839, Daguerre shows the details of the process at the Chamber of Peers in Paris. On August 19, the technical details were made public during a meeting between the Academy of Sciences and the Academy of Fine Arts at the Palace of L. (For granting the rights of inventions to the public, Daguerre and Niépce received generous life pensions.) )[3][4][5] When the metal-based daguerreotype process has been officially demonstrated to the public, the competitive approach of paper and salt-based calotype negative procedure
