Telephoto Oceanscape

Here is another composition during my visit to Monzamo here in Okinawa about 3 weeks ago.  I captured these two islands with my 70-200mm 2.8 lens.  I also had my Variable ND filter but don't remember how many stops I had it set for on this shot.  It is a 3 frame HDR +-2 stops but the average shutter speed was 15 seconds; that's why the clouds and water are so smooth.
