mystery, gangster, or horror films to emphasize contrasts between
light and dark images to emphasize the shadowy, dark worlds of
these genres.

bright lights with little variation of dark and light; often found
in traditional comedies.

behind the person or object to create an halo effect.
Colored lenses. Different colored lens are also used
to set the mood in a film based on certain semiotic or archetypal
meanings for colors. Red or yellow can be used to create a sense
of warmth while a bluish color creates a sense of coldness. In

predict future events were shown as ultra-white to create a sub-human
image.
