Kite aerial photography

Kite aerial photography

Kite aerial photography (KAP) is a hobby and a type of photography. A camera is lifted using a kite and is triggered either remotely or automatically to take aerial photographs. The camera rigs can range from the extremely simple, consisting of a trigger mechanism with a disposable camera, to complex apparatuses using radio control and digital cameras. On some occasions it can be a good alternative to other forms of aerial photography.

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 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.

hutter release and camera positioning

The shutter of the camera can be released in several ways, depending on the type of camera and complexity of the rig electronics, if used. Shutter release mechanisms include using a radio controlled servo to press the shutter release button, using an infrared signal or wired connection to instruct the camera to release the shutter, or by using the camera's inbuilt intervalometer. Ideally the camera is allowed to reach its final altitude before the shutter is released to avoid taking photos during launch.

Fixing the camera directly to the kite or line makes changes to positioning awkward. If the camera is fitted within a frame, this 'rig' can be designed to rotate horizontally and vertically and to change the picture format from portrait to landscape by rotating the camera. Adjustments to these angles can be made be manually setting the rig on the ground or by adjusting the rig while it is airborne using a remote control or an automatic controller in the rig. Commonly a radio control system, as used for model aircraft is used. The servos in these systems are readily adaptable to adjust rig positioning. Several automatic controllers have been developed that can take a photo, move the camera by a set angle, take the next photo and so on.


The most important aspect of any kite used to lift a camera is stability. Generally single lined kites are used as they allow very long line lengths and need less intervention from the flyer than steerable designs. Almost any stable kite design can be used to lift lightweight camera rigs (up to approx 500g/1lb). As weight increases, specific designs are chosen for their additional flying characteristics, such as line pull, wind range, flying angle and ease of launch. Widely used designs are parafoil, rokkaku, and delta (including variations such as delta conyne). Of these, the parafoil is most popular as it generates a strong pull for its size, and can be easily stored in a small space due to its sparless construction. Sparred kites such as the rokkaku or delta tend to fly at a higher angle than parafoils, which is of benefit when the space between the launch site and photographic subject is limited. A higher flying angle permits the kite to lift more weight, as more of the generated force is acting vertically.


The first kite aerial photograph was taken by Arthur Batut in Labruguière (France) in 1888. [ cite web|url= |title=The First Kite Photographs |accessdate=2008-01-08 |last=Benton |first=Cris ] [ cite web|url= |title=Arthur Batut Museum |accessdate=2008-01-08 |language=French ]

The famous kite image of San Francisco after the 1906 earthquake (right) was taken by an early pioneer in KAP, George Lawrence using a large panoramic camera and stabilizing rig he designed.

KAP today

With the advent of the internet, light and affordable digital cameras, radio control and microelectronics, kite aerial photography has really taken off. In latter years, kits have become available that enable a beginner to quickly assemble a functional KAP rig and start taking aerial pictures.Practical and commercial use of KAP is limited by the unpredictability of the weather (notably wind, sun and rain) and the fact that not every site is suitable to flying a kite. Launching a kite near buildings or downwind of trees can be problematic, due to heavy turbulence.The main applications today are amateur photography, art and archaeology. Attempts to commercialise KAP have so far been largely unsuccessful.
