1. Introduction to photography
The word photography together means "painting with light". Photography refers to the process of recording images with some special equipment. Generally, we take photos with 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.

3. Exposure process
When taking pictures, light enters the cassette through a small hole (more often, a lens group) and forms an image on the medium on the back of the cassette (relative to the incident direction of light). According to the actual light intensity and the photosensitive ability of the medium, the required light time is also different. In the process of lighting, the medium is irradiated by light.
4. Post-production
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.
