Aerial photographers take landscape or city photos from a high vantage point - usually in flight. This reveals an unusual camera view. The means used to fly often depend on the initial request. Airplanes and helicopters for a bird's eye view, ULMs and paragliders for shooting at low altitudes, hot air balloons due to their low speed that allows for repeated views, and more recently, drones, especially for military reasons. There is a wide range of applications, from cartography to art photography, including tourism and the army.
