Yann Arthus-Bertrand is a French photographer and environmentalist known for his aerial photography project "Earth from Above". He began his career taking photos of animals but became interested in aerial photography. For his photos, he uses helicopters or other aircraft to capture images from varying altitudes as low as 20 meters. To plan shoots, he works with scientists in different countries to identify important locations while obtaining necessary permits. Flights require good weather and funding. His photos are carefully logged, processed, and archived with descriptive captions to educate viewers about environmental issues.
