I was tracking this mother and cub near Churchill, Canada, for five days. Despite the bad weather, I returned to them after dinner on my last day of filming, as I had pre-visualised a shot in the Arctic sunset light. One little gap in the otherwise covered sky for a few seconds was my gift from Mother Nature.
