Don’t forget about post processing. The rule of thirds is your friend. With fast action it is not always possible to compose the capture the exact way you want. I always crop my soccer pictures where the ball or the player’s head or body falls on one of the “third” lines. Also pay attention to the horizon. Generally you want a level horizon so it doesn’t look like the Joker’s hideout in the circa 1966 Batman series. Although occasionally a tilted horizon can add dramatic effect. Look for fences, buildings, goal posts to help you rotate the picture correctly.
