Now here is a really superb idea. Capture some interesting parts of the British coast and then create GIFs which show what they look like when the tide comes in and out.
That's excatly what the photographer Michael Marten has done and you can see his work below.
Here's the blurb from his book Sea Change, which you can buy here
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 the twice daily rhythm of ebb and flood can dramatically transform the landscape.
