Three-shot sequence: Shot 1, medium shot, an old fisherman repairs a net on a pier at sunrise, 3 seconds; cut away to Shot 2, close-up of gulls circling over the calm harbor water, 2 seconds; return to Shot 3, the fisherman glancing up at the birds, 2 seconds. Same golden light and the same wave and rope sounds throughout.
