Artist Pearson doodles by LED light

Artist Pearson doodles animals, angles and human skeleton by LED light. He took photos for them. Every doodle took him 2-5 minutes. At the first picture, you will see two human skeletons are standing by sea. You maybe feel it really looks like a real couple standing by a sea. Seeing the angle, you will be astonished by how wonderful the light doodle is. At last, there is a human skeleton who loves the skateboard. With the help of LED light, you even feel the skeleton is good at skateboarding. Of course, I still want to know how Person control the time of exposure.
