Chiaroscuro Lighting
Lighting a scene with strong contrast between bright light and deep shadow, a style borrowed from old paintings called chiaroscuro. How lit a character is hints at their moral or mental state.
The Maltese Falcon
Arthur Edeson's photography sets the look that film noir would copy: faces half in shadow, rooms lit by single lamps, venetian blind patterns on walls. This kind of strong light-and-dark contrast is called chiaroscuro. Every character in the film has a shadowed side, on screen and in their morals. I feel like the lighting is telling you that no one in this world is fully in the light, the detective included.
Chinatown
John Alonzo photographs Los Angeles in the noir tradition of chiaroscuro, with a strong contrast between light and dark. The city looks sunny and corrupt at once, and many first-half scenes sit in deep blacks.
