When you mix lights, colour and shadows in just the right way, they will form a shape so exquisite that it will surpass anything deliberately made.
By controlling the light source, using the camera as the brush and the light as the ink. Sketching in a natural and random way, then you get one perfect combination of light and shadow without any artificial bias.
In this concept, I was trying to use lights as strokes in the Chinese calligraphy to construct another model of reading images, like reading the calligraphy art.
