Playing with the light and the location. Getting comfortable with the conditions of a place first then see how long can you expose the camera. Once you understand how much time you have before your picture blows out you can think in terms of concept. So this is pretty much a step inbetween getting the idea of the place and the conditions and a final planned lightpainting. So i pretty much just ran around and testet what goes. You look at the camera and go: Hey not so bad anyhow.
if you have more questions how its done ask me please.
