I had just watched 30 Days of Night and it occured to me that I hadn't experimented much with snow. The movie is dark and ominous and, let's be honest, sometimes it's nice to explore outside the boundaries of blue sky, happy people graphics. Something bad is waiting for our shadow man.
This is just a Photoshop composite (I didn't feel like modeling everything), but I picked up a few handy snow methods that have since been put to use on billable work. Thanks Josh Hartnett.
