> The idea was born from a mistake. One night near Death Valley, California, Wu set a camera to make a time-lapse series in the dark. A pickup truck drove by and washed out the scene with its harsh headlights. > At first, says Wu, “I was really annoyed. But when I looked at the images, I was fascinated. Here was artificial lighting in a natural environment.” The quote above indicates that Wu stumbled upon the technique by accident but, sandworm101 is correct, this technique has been known and widely used for decades. I know the technique as "painting with light" and a Google image search should convince any skeptics. Add "stars" to the search and you will see that the technique is often combined with star trails. Using drones is a nice enhancement. The criticism about originality doesn't make Wu's images any less spectacular.
