The Thames Barrier

Thames Barrier

This is a three exposure HDR of the Thames Barrier in London.
The Thames Barrier is the world's second largest movable flood barrier (after the Oosterscheldekering in the Netherlands) and is located downstream of central London. Its purpose is to prevent London from being flooded by exceptionally high tides and storm surges moving up from the sea. It needs to be raised (closed) only during high tide; at ebb tide it can be lowered to release the water that backs up behind it. Hope we never have to use it in anger.

The three images were put through Photomatix 4 as RAW files and set to produce a more natural output. I did a bit of tweaking in Photoshop (of course) but not too much thankfully.

Oh yes, and I shot the scene with a Polarising filter. Haven't used one of these for years and had all but forgotten how useful they were. A polariser is the one filter that Photoshop can't quite get to grips with.
