There are several types of documentaries:
- Fully narrated documentaries have voiceover throughout to educate viewers on what is happening. David Attenborough documentaries exemplify this type.
- Fly on the wall documentaries rely on observation with little commentary or narration, aiming to give viewers a realistic experience of being present. Police, Camera, Action is an example.
- Mixed documentaries combine interviews, observation, and relatable regional narration to advance an argument, adopting a modern news reporting style. Scratch demonstrates this type.
