Date of birth identified by photography

1839 August 19. Photography generally refers to photography. The word photography comes from Greek. Photography refers to the process of recording images with some special equipment. Photography generally uses mechanical cameras or digital cameras. Sometimes photography is also called photography, that is, the process of exposing a photosensitive medium by using the light emitted or reflected by an object. Someone once said an incisive language: the photographer's ability is to transform the fleeting ordinary things in daily life into immortal visual images. In June 2020, the National Copyright Administration issued the Notice on Standardizing the Copyright Order of Photographic Works, which clarified the copyright issues related to photographic works, intensified the copyright rectification in the field of pictures, and promoted the construction of a long-term mechanism for copyright protection of photographic works.

Generally, human beings take pictures with visible light, and cameras are the most commonly used. Because of different scenes and uses, cameras have many classifications. Generally speaking, a camera must have several basic components to ensure the exposure process, including: photosensitive medium, imaging lens, exposure time control mechanism, film cassette, storage medium, electronic photoreceptor and electronic storage medium. After photography is completed, the image information stored in the medium must be read by human eyes again through conversion. The specific method depends on the photosensitive means and medium characteristics. For film cameras, there will be chemical processes such as fixing, developing and enlarging. For digital cameras, pictures need to be processed by computers and then output by other electronic devices.
