Shutter 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 by 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.

Famous quotes containing the words shutter, release, camera and/or positioning:
“The rays which stream through the shutter will be no longer remembered when the shutter is wholly removed.”
—Henry David Thoreau (1817–1862)
“We read poetry because the poets, like ourselves, have been haunted by the inescapable tyranny of time and death; have suffered the pain of loss, and the more wearing, continuous pain of frustration and failure; and have had moods of unlooked-for release and peace. They have known and watched in themselves and others.”
—Elizabeth Drew (1887–1965)
“The camera relieves us of the burden of memory. It surveys us like God, and it surveys for us. Yet no other god has been so cynical, for the camera records in order to forget.”
—John Berger (b. 1926)
“Genius differs from talent not by the amount of original thoughts, but by making the latter fertile and by positioning them properly, in other words, by integrating everything into a whole, whereas talent produces only fragments, no matter how beautiful.”
—Franz Grillparzer (1791–1872)
