Lighting design is the process of creating the look of a shot that you use as a guideline for other shots in a scene to achieve consistency. As a starting point, it is useful to utilize reference materials such as photographs to generate ideas. These show how light bounces, diffuses, and reacts in different situations. Movies are very good source of lighting ideas. Studying still images from films to see where light is coming from or what colors are being used can help you create a more interesting lighting environment for your scene.
