It was an HBO documentary called "Naked World" following Spencer Tunick's last project to take nude photographs in every continent. I did tape it, but sadly I don't have vidcapping capability. His model in the Antarctic was his girlfriend, who had not modelled for him previously. And if you like ENFs, the Japanese sequence is a must-see!!
This sequence is (obviously) Paris, France, and a model who contacted him on the internet. She's not named in the documentary.
If you're unfamiliar with his work, check him out on
