Hints:
There are several tricks that may help you as you learn. One is to move
well back from the image you are trying to view. This will reduce the angle
that your eyes need to converge at.
Another is to hold up a finger or pencil in front
of the image about 1/3 to 1/2 way to the screen or printed image. Look at
the pencil but concentrate on the doubled images on the screen. Move the
pencil closer or further until they overlap to produce three images. The
center one should be 3D, but out of focus. Then you need to shift your focus
onto the center image without having it jump back to 2D (the tricky part :)
Another trick is to cut a square hole about the
size of the image (the left side, say) in a sheet of paper. Hold this about
half way between your eyes and the screen, centered between your eyes. When
done properly it allows each eye to only see its own image. Removing the
distracting extra images can help during the learning process.
Success: When
the sample image is in 3D you will see the frame around the picture as the
nearest thing (called the stereo window). The tree on the left is behind the
stereo window but the closest object in the scene. The tree on the right is
next further back. Then is the house and furthest is the sun.
Caution: Cross-eye viewing uses your eye
muscles in ways you aren't (yet) used to. If your eyes begin to get
strained, take a break and try again after some time.
