Take a look at this picture from Fogland Point in Tiverton, RI Mark Peterson decided to try taking some photographs with his camera lifted on high by a kite. Mark is that dot down there on the beach. This followed some experiments in rocket-assisted photography and was encouraged by some nice stuff done by a kite aerial photography enthusiast out West. This was a Samsung camera which could be set to take a picture every minute. The camera and mount weighed about 0.5 Kg.
More string is let out and the kite and camera move up and out.
Of course, the strings have to hold the camera up, so the camera pulls the string down where it is tied on.
