Abstract
A lighting stage comprising a floor and a turntable located on the floor and operable to rotate about a substantially vertical axis. The turntable has an upper surface to support an object, such as a vehicle, with a ceiling juxtaposed with and spaced from the upper surface. The ceiling has a downwardly directed reflective surface that extends laterally beyond the turntable. A peripheral wall extends from the ceiling to encompass at least a portion of the turntable and has an upper reflective portion and a lower absorbent portion. The upper portion and the ceiling smoothly merge to provide a continuously curved cove to provide the transition between the ceiling and the peripheral wall. A lighting assembly projects light on to the ceiling so that the ceiling and upper portion reflect and diffuse light towards the upper surface of the turntable to illuminate the object that is on the turntable.
