BuyingballoonsOn a warm summerday, with 50 euro worth of helium in three balloons…aerial photography using digital cameras. The setup was relatively simpel: A 3.1 megapixel camera, hanging from three balloons (50-70cm). Total weight of the setup was somewhere around 450 gram, the balloons had a pull of about double that. Two threads of 100 meters connected the ballons to us, so that we could get the camera to land again [via] Link.
