Torben, a friend of mine introduced me to the Lightpainting and here are some of the stuff we did.
Lightpainting
Link to pictures I would call it the fight, am I Son Goku? オラ元気だよ！ for lightpainting you only need a flashlight, best in different colors and a camera were you can change the shutter speed. Put the shutter speed to 20 seconds and paint with the light in the air then you get lightpaints. All pictures are not artifical made in the computer!
