There are three main types of documentaries: docusoaps which follow individuals over long periods of time like reality shows, reality TV which blends authentic material with entertainment content using techniques like observation, and "fly on the wall" documentaries where cameras are hidden to get an unseen perspective. Nick Broomfield is known for his minimalist, self-reflexive style where he appears on camera holding equipment. Stacey Dooley rose to fame with BBC documentaries highlighting child labor and aims to inform audiences and raise awareness of serious global issues.
