This picture was probably made with a light source coming from behind the figure in the middle. For one thing, he is silhouetted, and he would be illuminated if there was light shining directly on his visible side. Also, the light seems to disappear behind him at points, although it overlaps at others, suggesting it might have been coming at an angle. This is the only of the three pictures where the light is not directly the subject; however, it does serve to modify him. I would guess a long shutter speed for this picture, due to the volume and precision of the drawn light, particularly as this appears to be the only light source, due to the very orange colored background.
