What does camera's mean?

Camera s means shutter priority mode, and exposure mode is the same as aperture priority. In this mode, the camera metering system will calculate the required exposure value, and then it will determine the aperture and iso according to the number of shutters you choose. Because the shutter can be controlled, this mode is suitable for capturing some fast moving objects. Because the exposure is controlled by the SLR camera, even if the object moves to a dark background, the camera can quickly give the exposure value, which is very convenient and saves the time for adjusting the exposure.
