The document discusses the cinematography techniques used in the Blair Witch Project that contributed to its success. It used an experimental "gonzo filmmaking" style where the actors were sent into the woods with cameras and had to improvise their reactions, leading to very raw and authentic footage. This helped audiences believe the events were real. Some key techniques included amateur footage to give a first-person view, diegetic sounds from the video camera to make it believable found footage, and lack of traditional screenplay/dialogue to make the acting feel real. This unconventional style was pioneering for the time and led many audiences to think the actors were truly in danger.
