There are 7 main types of documentaries: docusoaps, reality TV, fly on the wall, mixed, self reflective, docudrama, and fully narrated. Docusoaps follow individuals or groups over a long period in an observational style. Reality TV shows real life drama for entertainment and information. Fly on the wall documentaries film subjects unaware with narration linking the story. Mixed documentaries use interviews, footage, and narration. Self reflective documentaries follow people who acknowledge the camera. Docudramas reconstruct past events. Fully narrated documentaries have narration throughout to explain the visuals.
