Drones add eerie halos to landscape photos in 'Lux Noctis'

Wu has used the drones in two ways for his dramatic, surreal photos. In the first technique, he attached LED lamps to 3D Robotics drones and set them off on GPS-controlled flights. He took the photos with a medium format Phase One camera while the drone was stationary, experimenting with the height, angle and distance from the subject. Once back home, he layered the photos together until the image matched his vision. For later photos, he created time-lapse exposures while the drones ran in set circles around the rock pinnacles, tracing out "halos" in the sky.
