Panning is a creative technique that can convey a real sense of movement in action photos. If you use a fast shutter speed to freeze a fast-moving subject, the picture can lack some of the drama that was there at the time, because the subject will look like a statue. But if you use a slower shutter speed and move (or pan) the camera at the same speed as your subject, then you can get the moving subject sharp in the photo while the background and any static objects become a smooth blur.
As well as adding a sense of speed, panning can help you capture a sharper shot of a moving subject and focus the viewer's attention on it, or simply disguise unappealing backgrounds. Whatever your intention, camera panning is a great skill to have, and the secret to achieving an impressive pan is practice. Panning requires good camera control, so there is no substitute for experience.
Track sports of all kinds are good subjects to practise panning on, because you get many attempts to hone your skills as the runners, horses, dirt bikes or racing cars pass by each lap. At home, children or pets playing in the garden are ideal opportunities to try capturing subjects in motion.
