I am planning a winter shoot with a model for late Spring. I've been doing research and I'm going between shooting on a glacier in Whistler where the mountain is normally open to summer skiing through early July or Iceland's glaciers.
I was worried about a model freezing on the ice but then I remembered this series from Ryan McGinley. Now that looks cold!
