This image invokes the great expanse of ocean wilderness and the solitude of a lone penguin, preening itself on a floating iceberg. Antarctica, because of it’s great remoteness and unique and extreme environment is a true wilderness. Moving through it’s waters on an the deck of an icebreaker is one continuous amphitheater experience. With a few lenses and camera bodies, the photographic options are many. I used the 100-400 often in situations like this for its great compositional flexibility with the zoom range of the lens.
