Aerial photography
From Wikipedia, the encyclopedia **Aerial photography** is the taking of photographs of the ground from an elevated position. The term usually refers to images in which the camera is not supported by a ground-based structure. Cameras may be hand held or mounted, and photographs may be taken by a photographer, triggered remotely or triggered automatically. Platforms for aerial photography include fixed-wing [|aircraft], [|helicopters] , [|balloons] , [|blimps] and [|dirigibles] , [|rockets] , [|kites] , poles, [|parachutes] ,vehicle mounted poles. Aerial photography should not be confused with [|Air-to-Air Photography], when aircraft serve both as a photo platform and subject.
