Re: [photo-3d] Want to Learn About Stereograms

[Ron Beck <rbeck@xxxxxxxx>]

I use a lorngette viewer, a hand-held plastic viewer with skewed lenses
that merge "wide-eyed" views into a single stereo image.

I learned how to cross-eye view by staring down at a tile floor and
merging the tiles.  The floor was a blue & white checkerboard styled
floor and I would concentrate on crossing my eyes and merging two of the
white tiles until I could clearly see the tiles.  You can tell that
you've achieved the proper viewing cross because the floor seems to move
a bit when you move your head and the tiles appear smaller than they
actually are.  In fact, I could perform what I call a "two-tier" merge. 
I would cross my eyes a bit and merge the tiles and then cross them even
more and merge the tiles again.  

I've gotten quite good at cross-eyed viewing and even use that method
when I'm trying to figure out those "what's different in these two
scenes" puzzles you see in the newspaper.

HTH,
Ron
