Check out the creepy effect seen in the video above, titled “Dancing Ghosts.” It was created by photographer Micaël Reynaud, who photographed a group of people during the day using long exposure times, and then interpolated the resulting photos into a real-time video.
Reynaud tells us that he was shooting with a Sony NEX mirrorless camera with a wide open lens. To allow for longer exposure times, he restricted the amount of light entering his camera using 2 neutral density filters and 1 infrared filter.
The photographs he captured had shutter speeds as slow as 2 seconds. During post-processing, he interpolated the motion blur-filled images into a video showing real time action. “The result looks like ghosts to me,” he says.
Reynaud shared this project with us after we shared a similar long-exposure project showing the Milky Way in real time.
