Mise-en-scene encompasses all visual elements that appear within the frame of a film, including setting, costumes, lighting, and staging of actors. It describes how these elements are arranged and their practical or aesthetic effects. Mise-en-scene covers four general areas: setting, lighting, costume, and staging. Lighting can be natural, available, or artificial and is used to achieve different moods. Costuming dresses actors according to their characters and can establish hierarchy or emphasize themes. Set design refers to the decor and furniture that dress the set and can bear deeper significance or emphasize themes.
