High-key lighting aims to reduce lighting ratios and shadows, creating an overall lighting design with low contrast between bright and dark areas. It is often used for comedies and action scenes. Low-key lighting creates a chiaroscuro effect using predominantly shadowy areas, and is commonly used for drama, horror and suspense genres. Lighting also helps set the mood and intensity of a scene. In the movie "The Third Man", the director used both high-key and low-key lighting - low-key in the bar scenes to create mystery, and natural lighting to depict an idealistic background as sunlight hits the character's eyes.
