What does camera professional mode S mean?
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 development. This technology is called photography, which is divided into general photography and professional photography.
The earliest camera structure was very simple, including only a black box, a lens and photosensitive materials. Modern cameras are complex, including lens, aperture, shutter, ranging, framing, photometry, film transmission, counting, self-timer, focusing, zooming and other systems. Modern camera is a complex product integrating optics, precision machinery, electronic technology and chemistry.
