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)
“As nature requires whirlwinds and cyclones to release its excessive force in a violent revolt against its own existence, so the spirit requires a demonic human being from time to time whose excessive strength rebels against the community of thought and the monotony of morality ... only by looking at those beyond its limits does humanity come to know its own utmost limits.”
—Stefan Zweig (18811942)
“In what camera do you taste
Poison, in what darkness set
Glittering scales and point
The tipping tongue?”
—Wallace Stevens (1879–1955)
“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)
