The document outlines 6 documentary styles described by Bill Nichols: poetic, expository, observational, participatory, reflexive, and performative. It provides examples and brief descriptions of each style. The poetic style uses subjective interpretations and creative editing. The expository style aims to inform by presenting facts, interviews, and narration. The observational style allows viewers to form their own conclusions through fly-on-the-wall footage without interference. The participatory style emphasizes interaction between filmmaker and subjects. The reflexive style exposes the documentary's construction. And the performative style addresses the audience emotionally through a narrative.
