Is it necessary for photographers to buy sports cameras?

This is necessary. Many times, good scenery and wonderful pictures suddenly appear, and the first time should be to record them.

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.

Digital camera is a kind of camera that uses electronic sensors to convert optical images into electronic data. It is a product integrating optics, mechanics and electronics, integrating the conversion, storage and transmission of image information, and has the characteristics of digital access, interactive processing with computer and real-time shooting.
