Documentary film began in 1895 with the short, unedited films of the Lumiere brothers capturing scenes of daily life. The first feature-length documentary was Nanook of the North in 1922, which staged scenes for dramatic effect. Direct Cinema in the 1960s aimed to present events objectively and verite-style, though editing still allowed control. Mockumentaries later exposed how documentaries can fake reality through conventions like voiceover, experts, and realistic techniques. Various modes include expository, observational, participatory, reflexive, and performative styles.
