COMPOSITION
Composing your scenes carefully in the viewfinder enhances the quality of your movies. You're already far ahead of the game if you can keep the background uncluttered, concentrate the camera on one center of interest at a time, and keep the horizon straight.
An uncluttered background helps focus attention on the subject. By filming from a low angle and using the sky as a background, or by shooting from a high angle toward the ground or water, you keep a lot of distracting elements out of your backgrounds. This is especially effective with close-ups of people.
