Light painting is a photographic technique in which exposures are made by moving a smartphone with the lightbrush app while taking a long exposure photograph.

You can choose between several shapes, sizes and colors.

Take your color from the colorwheel or take the random color mode.

Pause the light with one tab on the screen.

You need a cam with long exposure mode. A tripod is usually necessary due to the long exposure times involved. Alternatively, the camera may be placed on or braced against a table or other solid support. A shutter release cable or self timer is generally employed in order to minimize camera shake.
