On one of the mornings when we woke up in Patagonia, I came out of the tent to find everything covered in a soft blanket of snow. It was the middle of the autumn there, so the rich deep colors on the trees stood out in sharp contrast to white snow.
I grabbed this shot as quickly as I could before the snow started to cover everything up too much, which can tend make for a somewhat washed-out shot. I believe this photo was at f/2.8 with the 24-70 lens. That aperture helped the most interesting tree in the foreground to stay sharp while everything else stayed foggy and snowy (which it kinda was anyway).
