When was photography generally born?

Photography was generally born in 1839. 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. 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.
