Description
Polar bear open-water swimming photography requires the observation vessel to maintain maximum distance while using extreme focal length to document the bear without altering its behaviour — the polar bear regulation in Svalbard requires 300 metres minimum approach distance from vessels. This image was made from the observation platform of a polar expedition vessel using a 600mm prime with 1.4× teleconverter at maximum practical focal length, the bear swimming across a 200-metre open lead in the pack ice. The image resolves sufficient detail to show the bear’s swimming technique — the diagonal synchronised limb movement, the tilted head position for breathing, and the dense underfur visible below the waterline as a pale halo through the clear Arctic water. The lead edges — sharp ice boundaries — frame the bear in a compositional rectangle.
