Colors in this one are aka Rembrandt/Old Masters and work VERY well. I assume this is time lapsed, but am not sure; could be overlays? Some strange urge makes me want to identify the face, though, and not seeing it makes me feel somewhat uneasy. Maybe this sense of confusion is part of what you were trying to achieve?
The model in this photograph is a professional ballet dancer. Because his passion is movement rather than just posing, my objective was to create a still picture that showed his movement through the orangish blur created with tungsten lighting and daylight film. It was a 3 second exposure in which the dancer held the first pose (right arm up, left arm down) for the first second, then turned during the second second, and held the second pose for the third second. The first face is not identifiable partially because of the movement, but also because the second face (to the left of the first face) is partially covering it.
