Kite
aerial Photography (KAP) is about using kites to get aerial pictures from
unusual angles - in the space between the ground and where an aeroplane or
helicopter would be. Oh yes, one other thing, it's cheaper than a helicopter.
On
the left I am launching one of my kites, a Dopero100, with a 3m wingspan.
A Digital Camera is modified to allow it to be remotely controlled and pointed by setting it in a 'rig'. I have build a number of different rigs, some as light as 50grams, however the 'rig' shown right is for my 5Mpixel camera. Total flying weight is just over 600g.
The 'rig' is a mixture of electronic and mechanical construction, must be perfectly balanced, and made as light as possible.
The
'rig' is attached to the kite line via a bridle, consisting of
cord and pulleys to
keep the camera level. On the left I'm doing the final flight checks before kite and camera are allowed to rise into
the air.
From
the ground the camera can be steered and operated from controls on my waist (see
right). A video image of the pictures being taken are displayed on a mini-TV
round my neck (see left).
Once airborne the kite is normally untethered from the ground stake and
walked about to obtain the best camera angles.
And
here is the result, Blackness Castle, from the same day the shots were taken to explain how it all
works!
This page is a brief overview of how it all works, but there is a lot of technique to flying and details about how to build your own 'rig'. This web-site should give you a further insight into KAP, and some hints and tips that I have learned along the way.
