The document discusses different types of documentaries: fully narrated documentaries use voiceovers to provide context to visuals; fly on the wall documentaries seem like a natural, unobserved setting through editing and camerawork; mixed documentaries use interviews, observation, and narration; reflexive documentaries include the filmmaker addressing the audience directly; reflexive and participatory documentaries include the filmmaker as part of the footage focusing on their emotions; and abstract documentaries depict a subject in a non-realistic, unusual way.
