There are several stereo pairs on this page and on page 11-8. If you try to print out the page to get these images to cut apart and examine in stereo, the length of the page will require several printed pages. To avoid this, we have place most of the stereo pairs on a separate page, without text, which will reduce the number of printout pages needed. We extracted the pair below, showing mature topography in a dissected hilly terrain, from their proper positions in the full photos and placed them in juxtaposition, separated enough for stereo viewing. If you do not have a stereoscope, you still may be able to get the 3-D effect without one.
Many people can see in stereo with their unaided eyes.
Moving the fingers closer to or farther from your eyes causes the sausage to expand or shrink. If this doesn't occur for you, it means you either have some physical eye limitation, or you psychologically don't believe that you can do this. You may need to move your eyes in or out from the screen, as well. In effect, try to stare vacantly towards the faraway. So, if you do not succeed in seeing stereo on the screen, but have a stereoscope, you may print the above views and examine them on a table.
