Curiosity can be a risky business around the world's largest land carnivore.
When it comes to members of the bear family, aggression is often greatly exaggerated - except in the case of polar bears. They are one of the few predators on Earth that will actively hunt humans for food, so film crews need to have their wits about them if they're to witness the softer side of the arctic's supreme predator.

Polar bear walrus hunt
Male polar bears take on ever more deadly adversaries as their hunting fields diminish.
It took two years and three shoots to bag new perspectives on the obviously high-risk hunting strategies of polar bears. The effort paid off when this desperately hungry male polar bear, followed on his epic swim in search of food, was observed trying to predate fully grown adult walruses. Usually they would go after cubs, but increasingly desperate polar conditions are pushing them to ever more ambitious attacks.
Polar bear cubs
Filmed emerging from their den two years before, the cubs are now independent.
Situated in the middle of the highest density of polar bears anywhere, the crew's base hut was an unfortunate focus of attention for hungry males. At a more comfortable distance from the subject, the long lens capability of the HD heligimbal camera system allowed incredible scope for continuous transition between close up and wide shots without disturbing the bears.
Polar bear swim
Climate change forces hungry males to strike out ever further into the sea.
With no ground access for the camera crew on the breaking ice, the HD heligimbal aerial camera system really came into its own. The powerful HJ40 lens allows fantastic close ups from high above, pulling out to grand scale wide shots that illustrate the huge distances covered by the bear. Filming from so far above, the bear is wholly undisturbed.
