Lighting

Lighting comes from THREE different directions:
 * the front: Key lighting
 * the back: Back lighting
 * the sides: Filler lighting

Traditionally, 'happy' Hollywood makes wide use of all THREE at the same time - an effect which leaves no shadows or darkness, and is called HIGH KEY LIGHTING. However, film genres such as FILM NOIR use only ONE or TWO of these, creating a scene full of shadow and darkness (and often mystery and menace too).

 * In the opening scene of //Dead Again//, low-key lighting is used to build up tension and create suspense about what the murderer will do next.
