Kite Aerial Photography with a Picavet Rig
Lofting a compact camera on a single-line lifter kite, suspended beneath a self-levelling Picavet cross — a two-loop string suspension that keeps the lens horizon-true while the kite bucks — to shoot the ground from 60 to 120 metres up. Motorless, silent, and entirely at the mercy of wind and knot geometry. The craft splits cleanly in two: building a stable lifter and the levelling rig, then reading the wind window well enough to park the kite over the frame you actually want.
