The Mr. Fox image was made in Yellowstone National Park at the end of the day with little light. When the fox was initially sighted we were in a snow van cat headed for the Yurt Camp. The four of us jumped from the van and positioned ourselves so to have sightline to the animal but yet partially hidden by the van. The wind was around 15 - 20 knots with temperature approaching -10˚f. Mr. Fox cooperated with us for about 30 minutes until we had to escape the weather and got back in the van. Camera settings used were iso 250, ss 1/400 and f /5.6 with a 500mm lens.
