Documentaries aim to document real people and events to allow audiences to form opinions. They use techniques like observation, interviews, dramatization, mise-en-scene, and exposition. Documentaries can be fully narrated, fly-on-the-wall, mixed format, self-reflexive, or docudramas. They typically follow a beginning, middle, end structure and focus on conflict to drive the narrative forward. Elements like music, lighting, and visuals are chosen carefully to shape the intended meaning.
