There are several types of documentaries:
- Poetic documentaries highlight sentimental aspects of people's lives through camera shots, music, and editing to develop mood.
- Observational documentaries appear to film events as they unfold without interfering, leaving audiences to draw their own conclusions without narration.
- Expository documentaries talk directly to viewers, often with an author's voiceover.
- Participatory documentaries imitate the approach of participant observation where the filmmaker is involved.
- Reflexive documentaries acknowledge the filmmaker's presence and provide narrative about how the film was constructed.
