This was so wild. Never caught this kind of color before in a sunset. I really wonder if just having the CircPL filter on it would have been the same? I forgot that right before I shot this, I was on the beach shooting with a Sky 1A filter on the lens (which reduces blue and warms a little). I looked up and saw the sailboat moving towards the setting sun and I took off towards an outcropping of rocks that extends about 100-150 feet from the beach. Didn't want to risk not getting the shot, so I just grabbed my CircPol and put it on the lens with the Sky 1A. -=>Donald
