Duncan has created documentaries for programs with innovative science themes. The PBS series Wavelengths with Vicki Chandler is one example. He also directed a Lidar imaging project at a Mayan archaeological site in the jungles of Guatemala. Duncan also crafted documentaries on wildlife migration in the Amazon forests of Brazil and a survey project, both aerial and underwater, of innovative aquaponic operations off the coast of Baja California.

U.S. government agencies count on Duncan’s skill as a director and cinematographer. His productions include aerial surveys of tribal lands for the Alaskan Native Health Services. For the National Park Service, he produced a documentary that included aerial surveys of ten different national forests, including Yellowstone and Glacier. For another client, the University of Arizona, he surveyed the diverse biomes of the iconic Biosphere II structures with drones.

Daniel Duncan has also brought his cinematic skills to bear on challenging projects for corporate clients, including law firms in need of land surveys to resolve legal questions and liability for traffic accident injuries. He has documented corporate marketing events in Las Vegas, Cancun, the Bahamas and Costa Rica. And directed stories on agriculture ventures and architectural projects, including one that tracked building progress with innovative mapping software.

Some of Duncan’s documentary projects are important because they dealt with cultural heritage and history. For example, he directed a story that retraced the ancient buffalo kill zones on the Blackfeet reservation in northwestern Montana. For another heritage project, he documented the restoration of the interior of the San Xavier Mission, an important cultural heritage site in southern Arizona.
