Participatory documentaries

Participatory documentaries involve the filmmaker and is a collaborative process, engaging audiences to hear someones story by the filmmaker asking questions to someone /people about a story they are carrying out. This could be as minor as the filmmaker’s voice being heard behind the camera, prodding subjects with questions or cues — all the way to the filmmaker directly influencing the major actions of the narrative
The process involves designing a storytelling process which may reflect the voices and leadership of people impacted by an event or ongoing situation. Some communities / people may wish to ' expose ' a certain story, therefore are in a unique position to offer expert documentation, analysis and research. 
These documentaries are one sided and come from the directors point of view. They strive to show a story or message that the filmmaker wants the audience to see.
