In order to get creative with the illumination of your scene, you must first ensure the basic lighting is in place. The procedure for this, known as three-point lighting, is fairly simple and is used widely throughout television and film. To create a basic three-point lighting setup, you will need three lights, one of which can be somewhat brighter than the others.
The brightest light should be aimed at the front of your subject from a slight angle, and is known as the key light. This will provide the primary illumination for your scene. The second light can be placed to the side of your subject and will serve to fill in any shadows left by the key light. This light is known as the fill light. Finally, a light can be aimed at your subject's back. According to Mediacollege.com, this three point lighting system will add definition and provide a three-dimensional look for your scene. This technique is called the back light.
The easiest way to get creative with your lighting set up is to simply remove one of the lights from your three-point setup. Removing the fill light is a great way to intentionally leave shadows on the subjects face, creating a moody film noir look. According to Videomaker.com, this is the type of visual feel achieved by films like "Touch of Evil" and "The Maltese Falcon". You could also choose to use only the back light, turning your subjects into silhouettes.
Adding lights to your scene is another way of increasing its realism and stylistic beauty. Try using an open window in place of a fill light. As stated by Videomaker.com, using natural light can enhance your scene, so long as you match the color of your artificial lights as well. A lamp can be used in place of a back light and included in the frame for an additional dose of believability.
You can try adding colored gels to the front of your lights. Subtle colors will change the mood of a scene. For example, a blue gel will make your subjects look colder, while a red gel will give the illusion of warmth. You can experiment with other colors as well to give your scene a truly bizarre touch.
