This big guy put on a great show one evening up in the tundra, certainly one I won't forget - regardless of the imagery I was able to catch =)
This was shot with my favorite camera setup, one I honestly haven't used more than once in the past 18mos or so....
It's a Mamiya M645 1000S with a Sekor 500mm f/5.6, the film was Kodak Portra 400

One day I'll break out that beastly setup again, but for now I just use the 500mm as a shelf ornament because I'm out of film =P
