Ghost photos provide a visual documentation of the paranormal investigation done by a ghost hunting team. Cameras are supposed to be objectively neutral as to the existence or non-existence of the phenomenon called ghosts, and what they 'see' is considered to be more reliable than what eye 'sees'. Digital cameras are best suited for the purpose since they can give the instantaneous results. Digital photos can immediately be stored in a computer memory while the investigation is still going on and, hence, can improve on its reliability.
