Cinematography involves four main areas of focus: camera shots and angles, editing, sound, and mise-en-scene. Camera shots establish settings, characters, and objects using techniques like panning, tilting, close-ups, and mid-shots. Editing creates meaning by joining shots together based on principles like tempo and collage. Sound, both diegetic and non-diegetic, is added to set atmosphere and evoke emotions. Mise-en-scene encompasses lighting, set design, costumes, composition, and acting to tell visual stories through aesthetic elements.
