Sea Change: A Tidal Journey Around Britain by Michael Marten (18 pictures)
Since 2003 Michael Marten has travelled to different parts of the British coast to photograph identical views at high and low tide, six or eighteen hours apart. His beautiful and surprising photographs reveal how landscapes can be dramatically transformed by natural phenomena such as tides. From rocky shores to summer beaches and industrial estuaries, these imges record two moments in time, two states of nature and show landscape to be a dynamic process. Sea Change present 53 of these diptychs, arranged as a clockwise journey around Britain.
