I have photographed sharks in waters around the globe, and I always want more and yearn to peer deeper into their world. To feed my passion and to raise awareness, I developed a story about sharks for 'National Geographic' magazine.

For a photographer, sharks are a stirring subject, possessing a perfect blend of grace and power. They have been sculpted by evolution and are ideally suited for whichever ecosystem they inhabit, from coral reefs to the open ocean.

I still think there's a big part of the population that has a lot of misinformation about sharks. But I think it's beginning to change a little bit. As good information about sharks permeates popular culture, things may start to change.

Under the snowcapped mountains of Fiordland National Park, freshwater streams empty into the saltwater fiords, creating a unique ecosystem. This is a heavily wooded park, so the water in the streams is stained with tannin, a substance found in plants that makes clean water seem dirty, though it isn't.
