Mise-en-scene refers to everything that appears in front of the camera, including costumes, makeup, sets, props, and actors' positioning. It establishes important aspects like time period, location, and tone. Settings can be interior or exterior and also help set the tone and genre. Props are carefully chosen to support the film's meaning and avoid anachronisms. Costumes, hair, and makeup reveal characters' personalities, social statuses, and group affiliations. Facial expressions and body language convey emotions and attitudes. Positioning and use of space within the frame also communicate information to viewers. Visual effects enhance scenes through techniques like green screening.
