Why ghosts get 'spooked' by HD cameras
"Paranormal Activity 3," about amateur ghost hunters, is shot in a "found footage" style, in which the audience is treated to footage supposedly taken in real life from home videos and security cameras. It's also used real-life ghost hunting: Virtually all of the "evidence" for ghosts appears in the form of brief, ambiguous anomalies recorded with low-quality cameras (or good-quality cameras sabotaged by low-light conditions).
