You may know about light painting, which also known as light drawing or light graffiti is a photographic technique in which exposures are made usually at night or in a darkened room by moving a hand-held light source or by moving the camera. In many cases the light source itself does not have to appear in the image. The term light painting also encompasses images lit from outside the frame with hand-held light sources.
But I’m not gonna show you about common light painting generated from photography. What I’m gonna show you is 3D version of light painting wallpapers, which called light graphics. At first, I’m a little bit confused & had no idea what they are called. But finally, i found out that these wallpapers are 3D version of light painting/light graphics, which is definitely not generated by photography technique. It’s generated from 3D rendering technique.
