Shutter is a device used in camera equipment to control the time when light irradiates the photosensitive element.

Shutter speed is the time from opening to closing of shutter curtain.

The main function of shutter is to control exposure and "freeze" moving images.

The faster the shutter is, the more you can grasp the instantaneous static state of the moving object.

The slower the shutter, the greater the exposure; The faster the shutter, the smaller the exposure.

Shutter speed is not fast enough, which is a common reason for pasting.

It is recommended to shoot with a safety shutter.

Safety shutter = focal length X 2

Safety shutter is the shutter speed value for taking clear photos.

If the focal length is 100, the safety shutter is 1/200.
