Usually, you would want to avoid this effect by using
shutter speeds of 1/125 or faster. Certain subjects, however, are most effectively
photographed by deliberately capturing the blur. Sports photographers frequently make
use of blur to emphasize the speed or direction of movement.
There are two popular methods for doing this.
- Subject blur - hold the camera steady while the subject moves

If possible, you will want to bracket your shots, because the subject may move faster
or slower than you anticipate.
