The document describes 5 modes of documentaries: 1) Expository documentaries directly address the audience through voiceovers and use images and editing to support arguments. 2) Observational documentaries use no voiceovers or interviews, instead using handheld cameras to observe subjects unaware of being filmed. 3) Participatory documentaries involve interacting with subjects and sometimes include the filmmaker, using interviews and archived material. 4) Reflexive documentaries use fictional film techniques to elicit emotional responses and question authoritative voiceovers. 5) Performative documentaries include the filmmaker interacting and addressing audiences directly about an investigation or search.
