An exhibition of Michael Marten's comparative photographs, taken from identical positions at low and high water to capture tidal change experienced along Britain's coastline. The diptychs record the different tides side by side, giving visitors the chance to examine visual contrasts on long sandy beaches, white chalk cliffs, industrial estuaries and scenic harbours. Marten's photographs reveal the huge variety of tides: from just one metre on parts of the North Sea coast to 15 metres (the third highest in the world) in the Bristol Channel.
