Explanation:
Put on your red/blue glasses and gaze into this
dramatic stereo view from the
surface
of the Moon.
The 3D scene features Apollo 12 astronaut Pete Conrad
visiting the Surveyor 3
spacecraft in November of 1969.
The image was carefully created from two separate pictures
(AS12-48-7133, AS12-48-7134) taken
on the lunar surface.
They depict the scene from only
slightly different viewpoints, approximating the separation
between human eyes.
Combining images, one tinted red and the other blue-green,
with the correct offset,
produces the stereo effect when viewed using
red/blue glasses, the red filter covering
the left eye.
The color filters guide each eye to see
only the picture with the correct corresponding viewpoint.
The particular pair of images chosen also required a slight tilt to
optimize the stereo effect.
While you've
got those
glasses on, web sources of astronomy and space science
stereo images include the
Mars Path Finder archive, a
3D
Tour of the Solar System, and stereo experimenter Patrick
Vantyune's own set of stereo images from the
Apollo missions to the Moon.
