What you see is a combination of bodypainting (all the white plaster) and on top some Light Painting. I did use a black fiber brush with a flashlight attached. If you really interested you can also whatch my tutorial on it on YouTube. I think i will also upload it to D-Tube - Yes i should do that.
Anyhow the technique is fairly simple and straight forward once you seen it.
My model Ole had to sit still for about 30-60sec. then the photo was complete. The ISO was for that series at 1000.
Like i said if you interested in seeing how that works you can see it in my Youtube channel.
Hope you find it interesting. If you got question just ask.
