Default 3D Iris

I trick I tried that worked fairly well was to take one photo with my weight
on my left foot then take the second with my weight shifted to my right
foot.

How did you take the photo?



It's actually two photos. I shot the first one, then moved the camera a
couple of inches and shot the second one.



Aha, that's what I thought you did. ;-) Tricky. Well done!

Some years ago there was an article in a photo mag about making a tripod
gizmo to make this sideways movement easy and accurate. A "fat T" shaped
flat bar, about 1/8" thick, with the standard threaded hole in the (short)
leg of the T, plus a slot about 3" long (or longer) in the T-bar for a
thumbscrew to pass through into the camera's tripod mount. Mount the bar
on the tripod, then the camera at one end of the T. take the pic, loosen
the thumbscrew, and slide the camera over, and etc. It was up to you to
line up the camera with the bar each time. This is one of those projects
I'm going to make Real Soon Now. ;-)

NB that human eye spacing is about 2" to 2.5". This is therefore the
minimum spacing of the two pictures for a good stereo effect, but the
greater the spacing, the stronger the stereo effect.

You can also get a good stereo effect by taping two single-use cameras
together side by side, the lenses end up being about 3" apart.
