Documentary styles refer to the various approaches filmmakers use to present factual content. Common styles include expository, which aims to inform the audience through narration and visuals; observational, which captures real-life events without interference; and participatory, where the filmmaker engages with subjects directly. Each style influences how the story is told and perceived. Another popular style is performative, which emphasizes the filmmaker's personal experience and emotional connection to the subject. Docudrama blends documentary and dramatization, recreating events for dramatic effect. Understanding these styles helps viewers appreciate the diverse ways documentaries convey truth and perspective.
