Documentary film has evolved into diverse styles, each offering unique ways to capture reality. From observational approaches that passively record events to participatory methods involving filmmaker interaction, documentaries employ various techniques to engage viewers and present stories.

Reflexive and performative styles push boundaries, acknowledging the filmmaking process or using staged elements. Subgenres like expository, compilation, and docudrama further expand documentary's reach, blending factual content with creative storytelling to inform and captivate audiences.

Documentary Styles

Observational and Participatory Approaches

• Direct cinema captures events as they unfold without intervention, allowing the viewer to draw their own conclusions about the subject matter
• Cinéma vérité involves the filmmaker actively participating in the events being documented, often through interviews or provocative interactions with the subjects (Chronicle of a Summer)
• Observational documentary aims to capture reality as it happens, with the filmmaker acting as a passive observer and avoiding any direct involvement or manipulation of the events being filmed (Salesman)
• Participatory documentary features the filmmaker actively engaging with their subjects, often through interviews or by sharing their own experiences and reflections on the topic at hand (Sherman's March)

Reflexive and Performative Techniques

• Reflexive documentary draws attention to the filmmaking process itself, acknowledging the presence of the camera and the subjectivity of the filmmaker's perspective (The Man with a Movie Camera)
• Performative documentary emphasizes the subjective, emotional, and expressive aspects of the subject matter, often through the use of stylized or staged elements (The Act of Killing)
• Poetic documentary prioritizes aesthetic and atmospheric qualities over traditional narrative structure, using imagery, music, and associative editing to evoke emotions and ideas (Koyaanisqatsi)

Documentary Subgenres

Expository and Compilation Approaches

• Expository documentary relies heavily on voice-over narration and direct address to the viewer, presenting a clear argument or perspective on the subject matter (The Civil War)
• Compilation documentary is constructed entirely from pre-existing footage, such as archival materials, news clips, or other films, which are edited together to create a new narrative or argument (The Atomic Cafe)

Dramatized Reenactments

• Docudrama combines elements of documentary and fiction, using actors to recreate real events or experiences based on factual research and accounts (The Thin Blue Line)
• These reenactments aim to provide a more immersive and emotionally engaging way of exploring historical or contemporary issues, while still maintaining a commitment to accuracy and authenticity
