From within

A Second on the Severn Sea 1 from robin jenkins on Vimeo.

In this clip, you can see the view from one of the cameras inside the rig. In the first half of the film you can see the interior of the glass tank slowly misting up. This was caused by the tiniest drop of water and the warm summer sun. Later, the evening shots show a much crisper and defined view. So watch to the end.
