Shooting For Action
How to get high-impact photos of the wide world of sports
For sports with movement that’s less predictable, by using zone focusing, you can set up your aperture and focus to cover an area where your subject will most likely end up.
NEED FOR SPEED
When shooting action shots of sports with swiftly moving subjects, your most important teammates are shutter speed and aperture. Shutter speeds give you the ultimate control over sharpness, and for the quick and erratic movements that you find in most sports, you want to use a very fast shutter speed indeed. In general, a shutter speed of ½50 sec. is the bare minimum for freezing action, though most photographers recommend going much higher.
The wider your aperture, the shallower your depth of field will be. This will keep the background and foreground surrounding your subject out of focus, which helps to bring your viewer’s attention to the subjects in your image. The flip side of a shallow depth of field is that your subject will fall out of the area of focus more easily. So keep it tight for visual impact, but give yourself enough leeway for movement.
Autofocus on modern DSLRs is incredibly quick and accurate, even with rapidly moving subjects. Still, sometimes there will be situations where manual focus will work better, especially when working with the incredibly fast speeds of car racing or bike racing. In these situations, panning with or following the subject will give you great focus.
