The document discusses key elements of film production techniques, including mise-en-scène, shots, camera techniques, and sound. Mise-en-scène refers to everything visible within the frame, including sets, props, actors, costumes, and lighting. Shots are the smallest unit of film like letters are the smallest unit of a novel, and longer shots imply greater importance. Camera angles, movements, focus, and lighting can be used to reveal information about characters and the narrative. Sound is divided into diegetic sounds from within the story and non-diegetic sounds from outside the story like music and voiceovers.
