There was natural light falling through a vent in the ceiling of this subterranean vault, I lit the ceiling, walls and floor with an LED torch which to the eye has a white light, but playing around with the White Balance in CS6 brought out a pleasing blue hue. Thanks to Roland for holding the pose without moving for 30 seconds.
