The Frenchman Roger Aubry realized a very sophisticated system for kite aerial photography. It was possible to change the framing by moving the camera from the earth, thanks to the energy supplyed by a little dynamo. In this way it was not necessary to recover the kite each time that the operation was needed.
The camera was able to shot a sequence of ten images, on ten different plates ; when the shutter was released, on each plate, were impressed the values of the eight and inclination of the camera in that very istant.
