Position can also be critical. For high school football, I stand either 10 yards ahead of the play or five yards behind. In college and pro football, I move to 15 yards ahead and 10 behind, or head-on in the end zone. In basketball, I stay on the right side of the court simply because the referee always stands on the left side and will get in the way of your shots. In basketball, the digits on a player's numbers never exceed the number five. This is because, when a referee is calling out a foul, he's typically holding the basketball in one hand and can only use the other one to call out the numbers, so they never exceed five. In many track and field events, lower angles are more to my liking. The backgrounds tend to be cleaner and again, it's unusual and makes a more visually interesting image.
