I think the photographer was able to full painting with light photo off by having a great knowledge on how setting, ss, ap, iso, and Lense should be for this type of picture. The first thing I think he did was having his shutter speed at maybe at 4 seconds. The second thing he probably did was having is wide Lense of a 35mm fisheye. A third he did was to have a high aperture of approximately f/16. Another thing he did was to have his ISO at 200 to make the background even darker but not 100 because it will be too dark. Also there looks to be a light source coming from a hallway, red and white finger lights. It is so eye catching because of the patterns the light were going in.
