There are seven main types of documentaries: fly on the wall, docusoaps, mixed, self-reflective, docudrama, fully narrated. Fly on the wall documentaries involve covert filming with no interference and no interviews to observe natural behavior. Docusoaps are long-running observational series that follow groups or individuals. Mixed documentaries combine interviews, footage, and narration to link different stories. Self-reflective documentaries feature narrators contributing their perspectives directly to the camera. Docudramas reconstruct real events through reenactments. Fully narrated documentaries involve a narrator describing the entire film from beginning to end.
