There are several forms of shutter speed, what role does it play in photography?
In traditional cameras, especially mechanical cameras, the shutter speed is usually expressed as B/2/4/8/15/30/60/125/250/500/1000/2000, which is actually1.
..... 1/2000 seconds. Among them, door B means to control the exposure time independently, hold down the shutter until necessary, such as shooting night traffic, fixing the camera, and holding down door B for about 15 seconds before releasing, leaving beautiful bright lines on the negative.
The slower the shutter speed, the greater the exposure, and the faster the shutter speed, the smaller the exposure.
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 is, the more it can show the motion process of dynamic objects.
I suggest you shoot some streams with different shutter speeds, and you can see the film at a glance.
