Here's a great accessory for taking photos in the cold; Lululemon gloves. The tips of the pointer finger and thumb can be easily slipped over your fingers which allow you to turn knobs yet keep your hands from freezing. I love them! I think they are actually meant to control your iPod but it works wonderfully with your camera too!
{The other thing to remember when shooting in the cold is that your battery will drain way faster! When I climbed Mt. Kilimanjaro, I hiked with my camera batteries tucked under almost all of my clothes.}
