Getting great action shots depends on a number of things: the speed of the subject, the direction it’s traveling, and the distance from the camera. While these can be large variables, the most important factor is a fast shutter speed. For a person running, 1/250 sec. should do the trick. For faster moving subjects, such as a moving car or a skate boarder, as shown in Figure A, you’ll have to go to at least 1/500 sec.
