Kite Aerial Photography: Picavet Suspension
The picavet suspension attaches to the rig and keeps the camera relatively level to the ground no matter what the kite is doing. It also dampens the motion induced by the kite moving in the wind. It is an aluminum cross with 4 small single-block pekabe pulleys, one on each end. I have about 60 feet (20 m) of dacron line threaded through each of these four pulleys, and through a double-block pulley on each of the two aluminum connectors. The connectors are based on Brooks Leffler's design, which allows me to quickly attach / remove the rig from the kite line.
