Cross-Key Lighting
Two keys from opposite sides with little fill, so a face is caught between sources and the scene feels adversarial.
What it does
Cross-key lighting uses two keys from opposite sides and little or no fill, so both cheeks catch and a darker valley remains down the centre of the face. It is the lighting of rooms with windows or lamps on two walls, and of conversations that do not want a single heroic side. Emotionally it feels adversarial and alert: the person is caught between sources, with nowhere fully to hide. Jeff Cronenweth lit the deposition suites in The Social Network this way, the legal battle written as two competing windows. David Fincher and Cronenweth returned to dual sources throughout Gone Girl, so domestic space never quite became a nest. Use it for argument, interrogation and open-plan interiors that have honest architecture on two sides. Do not use it when you need a romantic key-and-fill courtship of the face, because the double catchlight and the central shadow will read as conflict even if the scene is tender.
