Milestones in underwater Photography

Called "the Audubon of this century" for the variety and proficiency of his marine photography, photographer David Doubilet has mastered the use of light to produce what one National Geographic editor calls "customary superb Doubilet shots." Among them is this, a light-drenched photo of sea lions swimming in the waters of the Great Australian Bight in the Indian Ocean.
