A year or two ago I was shooting long exposures on the beach at Swanage in Dorset, England. Rolling waves, wooden groynes and sparkling, pristine sand in my foreground. I had about ten feet of billiard table smooth, unspoilt sand in front of the camera and about thirty feet of empty beach behind me.
A gentleman walking along the beach looked at me, looked at the camera and then proceeded to walk in front of me and through my shot, ruining the sand as he went. He knew full well what he was doing, the self-satisfied smug look on his face said it all.
