33 Old. I've tried this shot several times. A historic, over 100 year old, rig that still runs to operate a number of oil wells - pretty much original except that the steam engine that originally ran it burnt down and was replaced with an electric motor quite a few years ago. Inside, only light is through the windows so needs multiple exposures and then capturing the motion of the wheels and arms is tricky. This was the first one I've tried using HDR Efex Pro - still not quite right but working on it!
