Since I had been working some much with old stereographs and converting them into 3D anaglyphs, I wanted to try my own stereographs. My first attempts were OK, but not great. I was attempting to use one camera to create two images, but the results were often unpredictable.
I did learn a a trick with this process, though. Fairly decent results can be obtained by first putting your weight on your right foot and snapping a shot, then shifting your weight to your left foot and shooting. That gives just about the right amount of separation for a good stereo image.
Unfortunately, this process has some drawbacks. First, it’s awkward if you want to get a shot that’s not easily taken from a standing position, say, a low show of flowers or a still life. Also, it won’t work if there is any movement. You need some way to snap two images simultaneously.
I did come up with a way to do just that. I found a couple of VERY cheap cameras online. My only criteria was that the cameras had to have at least 3 megapixels, have a tripod mount, and have a self-timer. My solution was the Global Point Trekker camera, which cost me a little over $10 through Amazon.com (ignore the $34 price on their home website.)
