lots of very interesting shots, let my just take #2 / #7400: Very unusual long exposure with high waves. You must be on some piece of rock.
Hi Frank, thanks for the interest.
Nice try but wrong.
I was snorkeling in deep water, with the camera in an underwater enclosure. I actually had to keep a very fast shutter speed because I was bobbing in the waves.
The wavy line you are seeing roughly one third up the frame is the water-air boundary with the water surface.
