Travelling through the south island of New Zealand one is struck by the scale and beauty of the glacial landscape. Milford Sound is often hidden in a thick mist and opportunities to make photographs are few and far between: these were taken on a rare day of clear skies and sunshine. The only way to travel and see the Sound is by boat: sailing out to the mouth of the fjord and back, the sheer cliffs and waterfalls to either side are immense. Moving slowly under the waterfalls in brilliant sunlight, rainbows are formed below the powerful chutes of water and light picks out moss clinging to the fine edges of rock escarpments.
