Photographer Benjamin Von Wong had quite a few obstacles while working on his underwater project. Some of those are straightforward: having only a certain amount of oxygen, cold water, a small window of natural light, nonexistent underwater communications, and scaring sharks away. But tying down a model underwater proved to be the most challenging. Watch how it was done in this short film and learn what the "Shark Shepherd" wants the world to know about the future of sharks.
