Offense? Not a bit of it! Folks unable to handle parallel gaze or crossed-eyed viewing must rely on one sort or another of stereoscope to aid them in parallel gaze viewing to perceive 3-D.
Don't feel badly, Scotty, it's really not a character flaw!

When I was barely into short pants my grandparents had an immense collection of cards of sterio-image pairs of an incredible variety of scenes and subjects, and a wooden stereoscopic viewer - which my grandmother always had to use. My grandfather, on the other hand, simply held the cards up before his gaze and never had to use use the viewer for the
3-D effect.... His opinion (not PC today...) was that is was "...mainly for the ladies to use". Didn't take long for the novelty of the viewing gizmo to wear off and to realize that his method was lots more convenient than using the viewer.

Different strokes for different folks!

Hi, Don,
I wondered if anyone experienced with topographic photo recon images would show up. Sure glad to get your input. There are aspects of these images that are fascinating, but that I don't completely understand.

I'm particularly curious if you got the 3-D effect from the receding fence pair and the " sage brush" with Monument Valley in the BG.

As for the plug-and-wires image the lens offset was only about 1 1/2". I'm not at all sure about why the shift in arrow position in depth...

Also curious if you are using parallel gaze or crossed eyes when viewing these.

Any input appreciated. This is all new to me and gun to experiment with.

Dave, Trying again and hoping UHH doesn't eat my reply. I did, indeed, get the 3D effect from both of those images. I use the parallel gaze technique to view stereo pictures. When we were learning air photo interpretation a number of us trained ourselves to view the photos without the stereoscope. It was easier to get a general view of the ground without the stereoscope getting in the way. Of course, when we got down to the counting and measuring we used the stereoscope for the magnification. We trained ourselves to use the parallel gaze method by holding a sheet of paper cardboard between our eyes to avoid crossing our eyes. Soon we were able to "see stereo" without the cardboard. Once we were able to see stereo without any aids, we amused ourselves by making stereo drawings - two sets of concentric circles side by side, with the circles in one set off set slightly to one side will give the effect of a cone when viewed in stereo.
