What is light and shadow painting?

Light and shadow graffiti, also known as light painting, light graffiti and photoelectric graffiti, is a photography technology that moves a hand-held light source or camera in a dark room at night to produce light mapping effect. In most cases, the light source does not have to appear in the work. Relying on the movement of light to create wonderful images, photoelectric graffiti art was born. This kind of performing art, which was born in the street, has now set off a craze around the world.

In most cases, the light source does not have to appear in the work. Producers use the movement of light and superb photography techniques to create incredible images. Works can be made in the street, indoors, in nature and in the studio. From the media of artistic expression, light graffiti can surpass the traditional media and attract a large number of audiences in various media such as plane and network. Different from traditional photography and graffiti, light graffiti is sometimes produced as a performing art, and sometimes it is only captured through photography and video, but either way, it will produce incredible scenery.

Artistic principle

The principle is to adjust the shutter of the camera very slowly, then wave the shape with a luminous body, and then the camera records the movement track of the light spot, which is what you see. Take a photo with the camera (shutter is open or not) and move it on the screen with a laser pointer similar to the "infrared" we often play. The camera records the motion track of the reflection point, closes the lens after completion, and then finishes after PS.
