Mister 3D taught me how to take 3d photos. It's pretty easy actually. All you have to do is take one photo with your weight on your left foot, and then shift your weight to your right foot, and then take another photo. This estimates the distance between your eyes, to get two photos of the same thing properly offset. (Mister 3D has a cool rig where he has two cameras hooked up to the same trigger, so he can take 3d action shots. I can't do that with just my one digital camera, so I'm limited to relatively stationary stuff.)
To view these 3D images, you need to use some kind of viewer that will make your left eye look at the lower image, and your right eye look at the higher image. I use the PV4000 View Magic print viewer which is available for (as I write this) $35+ shipping from Rocky Mountain Memories.
After you get the viewer, you need to make the images appear on your computer monitor at approximately the same dpi or pixels per inch that I created the pictures at. This is kind of annoying, but hey, if you went to the trouble to get a physical viewer, you might take the time to set the resolution on your computer.
Go to your monitors control panel, or monitors properties panel. If you have a 19" or 20" monitor, set your resolution to 1024x768. If you have a 17" or 16" monitor, set your resolution to 800x600 or 832x624 depending on which choice you have. I don't know if you'll be able to see enough of the image for it to work, but maybe if you make your browser fullscreen, you'll be able to -- the active part of the image is 532 high generally. If you have a larger monitor type, you can extrapolate from what I listed here to get the right size for you. Basically, you're looking for about 72dpi. (The 3D probably won't work on a 15" or smaller monitor.)
Once you've done that, click on an icon over on the left, and take a look. The icons that the 3D works better for are closer to the top, the more difficult ones you may not want to bother with are last.
Some people find some images easy which other people find hard. Also, sometimes it works better to be about 4" from the screen, and sometimes it works better to be at about an arm's length.
