As we climbed the steep spiral back down the lighthouse, I spied this one window that was positioned perfectly for an inside-outside shot. I exposed for the exterior scene, and let the incoming rays light up the interior bricks. I cranked my ISO up to 800 for potential interior shots, and let it ride at 800 for this view, captured at 1/800 f6.3 at 24mm to give some deeper depth of field. Since my shutter speed was much faster than my focal length, there was no need to employ OS for this shot. But that being said, there was absolutely nowhere to set up a tripod for the frame–so a multiple shot sequence for HDRI photography was totally out of the question!
