As light painting is getting more and more popular, light doodling has become a new kind of graffiti art. Just like the magnificent fireworks show, this colorful visual spectacle can also leave an unusually deep impression. The main characters of light doodling are the light sources, including flashlights, bicycle lights, and colorful LED (light-emitting diode) lights. All these light sources are used to "draw" beautiful pictures, which are captured by photographers using cameras, thereby creating these amazing light doodling works.
