What are the three elements of photography?

The three elements are: exposure, focusing and composition.

1. exposure: exposure refers to the amount of light that enters the lens and shines on the photosensitive element during photography, which is controlled by aperture, shutter and sensitivity. It also means that something is exposed or exposed.

Second, focusing: focusing refers to adjusting the focal length when using the camera, which is called focus in English. Generally, digital cameras have various focusing modes, namely, automatic focusing, manual focusing and various focusing modes.

Third, composition: photographic composition is a "theory" that people sum up from a set of practical experience based on successful photographic works. Photographic composition can help beginners get started quickly.

Photography classification

Still life photography: Compared with portrait photography and landscape photography, it photographs inanimate objects (this concept of inanimate objects is relative, such as fish and shrimp caught from the sea, melons and fruits picked, etc. ) and man-made objects that can move or combine freely. Mostly take industrial or handmade products, natural inanimate objects and so on as the shooting theme. On the basis of truly reflecting the inherent characteristics of the subject, the subject is represented as a photographic work with artistic beauty through creative ideas and photography means such as composition, light, tone and color.

Still life photography has a vast world in material selection. After selecting materials, we can deal with these objects at will, because objects are inanimate and can move from multiple angles at will to achieve our creative intention.

Portrait photography: Portrait photography is different from ordinary portrait photography: Portrait photography takes the description and expression of the specific appearance and manner of the subject as its primary creative task. Although some portrait photography works also contain certain plots, they still mainly show the appearance of the subject, and a considerable number of portrait photography works only explain the image of the subject without specific plots. Figure photography focuses on the events and activities that the subject participates in, and its main task is to show the specific plot, rather than showing the appearance and behavior of the subject with vivid images.
