Mise-en-scene refers to everything visible within the frame of a shot that can provide contextual information to the viewer. There are six key elements of mise-en-scene: color, costume, props, set/location, blocking/performance, and lighting. Color, costume, and lighting are used to convey meanings like innocence, evil, class, and mood. Props provide context for scenes and influence how actors should perform. Blocking/performance covers actor positioning and movement. Location can be purpose-built or real places.
