What are the advantages of slow shutter speed?

1 A high shutter can take a clear picture of moving objects, for example, children are more active, and a slow shutter will blur. For example, cars, athletes shooting and birds, the sooner the shutter, the better, otherwise the shooting will be blurred. The accurate shutter speed depends on the moving speed of the object. There are also some solidified water droplets in the advertising picture taken with a high shutter.

2. The special use of slow shutter, such as shooting water with 1/4 or slower shutter, will have an ethereal feeling. For example, when the camera moves with a running horse and presses the shutter in the middle of the movement, it will take a dynamic picture with a clear horse and a blurred background.

3 shooting static scenes, generally there is not much difference, digital words, too slow will increase noise.

4 cooperate with the aperture, for example, if you want to blur the background, the aperture will be large, and the shutter will be fast. If you want to shoot a large depth of field, the aperture will be small and the shutter will be slow.
