I built the sleigh out of 5/8" plywood. I had my wife stand in front of Ralph the dog, just out of the frame, and get Ralph's and Matt's attention so that they'd look straight ahead. This was my first and only photo session with an old dry ice fog machine I had. It was the type used by rock bands, and consisted of a 55-gallon barrel with a heating element, two baskets to hold the dry ice, a fan and a dryer hose. Once we had everything in place, I turned on the fog. For the next ten minutes I could see absolutely nothing. We had enough fog to fill a concert hall packed into my studio. Once it started to break up, I shot this picture through the cloud. (I also had put a Tiffen Fog #2 filter on my camera, in case the fog wasn't thick enough!)
