==Camera rig and stabilisation==

The camera can be attached directly to the kite but is usually secured to an adjustable rig suspended from the kite line at a distance from the kite. This distance reduces excessive movement being transmitted from the kite to the camera and allows the kite to be flown into higher, stable air before the camera is attached. If possible, the camera is set to a high [[shutter speed]] to reduce [[motion blur]]. Cameras using internal [[image stabilization]] features can increase the number of sharp photos. In order to take photographs that are oriented correctly with the horizon, a suspension method is used to allow the rig to automatically level itself under the kite line.

===Pendulum suspension===

This simple levelling method involves suspending the camera from a rigid length of material below the kite line. [[Gravity]] naturally keeps the rig level, irrespective of the angle of the kite line. The pendulum will [[oscillation|oscillate]] due to movement from the kite line and wind pressure, but the camera will remain steadier and more level than without a pendulum.

===Picavet suspension===
A Picavet suspension, named after its French inventor, Pierre Picavet, consists of a rigid cross suspended below the kite line from two points. A single line is threaded several times between the points of the cross and the points of attachment to the kite line and the rig is attached to the cross. The Picavet line runs through eye hooks or small [[pulleys]] so that the weight of the rig causes it to settle naturally into a level position. The dimensions and shape of the Picavet have been adapted many times in attempts to increase stability or to improve portability.
