I am a big fan of the Waiheke island ferry. There are always interesting things happening on the water that make for a good photo. I liked the cloud formations in the above photo, which seemed almost like lightening coming down to hit the mast of the yacht. I like photos with a lot of empty space, focussing on a few smaller elements in the middle, in this case the island and the boats.
The Waiheke Island ferry takes about 40 minutes to get to Waiheke. It is a beautiful trip through the Auckland harbour, passing many smaller islands on the way to Waiheke. There are usually plenty of sailing boats and yachts on the water which make sure there is enough food for the lense.
