The purpose of the camera

Usage: According to the performance characteristics of different products, digital cameras can be divided into household, quasi-professional and professional cameras. Bian Xiao feels that for the mass users, we have not studied professional photography knowledge and are not experienced photographers. Cameras are generally used for daily shooting, so there is no need to choose so-called high-end products. A card camera is enough.

A camera is a kind of equipment that uses the principle of optical imaging to form an image and records the image with a negative. This is an optical instrument used for photography. In modern social life, there are many devices that can record images, all of which have the characteristics of cameras, such as medical imaging equipment and astronomical observation equipment.

After the light reflected by the shot scene is focused by the camera lens and the shutter that controls the exposure, the shot scene forms a latent image on the photosensitive material in the camera box, and forms a permanent image after being developed and fixed. This technology is called photography, which is divided into general photography and professional photography.
