This document discusses the different modes or styles of documentary filmmaking. It identifies and provides examples for several modes: expository, observational, participatory, reflexive, poetic, and performative. Observational documentaries aim for cinematic realism using available light and small cameras to create films with a fly-on-the-wall perspective. Reflexive documentaries make audiences question assumptions by acknowledging the filmmaker's role. Poetic documentaries emphasize visuals over narrative to create an impression through techniques like shot design and rhythm in editing.
