You may want to check out the 3-D photos on my web page, under
"Changing Showz - may appear here"... (and the two methods I
describe for direct-viewing, without gadgets). These were taken with
two cameras on a bar. Remember that in order to show 3-D effects,
the photo must contain large enough detail at different distances
to be distinctly seen. Also, unless the two cameras are widely
separated, there will be little 3-D effect in distant views
(the separation in the cloud photo is a couple of hundred feet,
the rest are about 8", which exaggerates the 3-D effect). BTW,
you can take stereo images with a single camera, if you frame
each image (taken at least a few inches apart) carefully, and
nothing much changes in the intervening time between frames.
