Daniel Sullivan is a photographer, filmmaker, and author who has spent more than twenty years documenting the land, culture, and ocean ecosystems of Maui, Hawaiʻi. His work spans aerial, underwater, and wildlife photography, with humpback whales and coral reefs at its heart. His films Koholā and Coral Guardians have earned festival recognition, and his images have appeared across National Geographic Channel, BBC's The Green Planet, Discovery, and Outside Magazine. Shooting on Nikon systems and Ikelite underwater housings, he pairs technical precision with a conservationist's eye, creating work that invites viewers to protect the fragile marine worlds it reveals.
