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.
