I learned how to make a stereoscopic image from a fellow photographer today.

In lieu of posting the image here, I'll just post a link to the photo in my personal gallery. It's one of those "jittery" ones, so if you have eye trouble, or you have epilepsy, don't click on the link, k? Don't say I didn't warn you. It's cool, but it'll give you a headache if you weren't expecting a photo to move:

Stereoscopic Trees 1

It's far from perfect, but I think I'm on the right track. Now, as soon as the boyfriend wakes up, I'm going to make him stand in the front yard so that I can see what a human subject looks like with this method in my inexperience.

Hello, found you via AD. Was wondering if you would mind explaining steroscopic images. Photography is an amateur (and I mean very amateur) hobboy of mine. I know I can probably look it up, but I'm just too lazy :)

The basic premise/point of a stereoscopic image is to make an object in the foreground appear to be three-dimensional by messing with the perspective of the background.

Remember those ViewFinders? They utilize stereoscopic "technology" by having two perspectives of the same image in either eye. When you force the eyes to look at two separate things without allowing them to see what the other is seeing (i.e. by putting a barrier between the images and between your eyes), your brain is forced to reconcile them, and thus you get 3-D imaging.

The problem with that sort of thing is that you can't really show it on the internet. So someone came up with the bright idea of alternating the two images at a high-ish rate of speed - which is where you get images like the one I (sloppily) made. I used a single camera with a single lens, digital, to capture my images. Ideally, I would have a stereoscopic camera with two lenses spaced about an inch apart, which would offer two perspectives with a single shutter depression, thus allowing the primary foreground image to be in one spot on the final .gif while the background flips back and forth. actually has some decent photos regarding the stereoscopic stuff (including one taken of the photographer that told me about this method, in which he looks as if he's surfing the ground during an earthquake), but their description of how to do it with a single-lens camera is kind of lacking...I had to do it by trial-and-error.

I think it's here.

Have fun and good luck! :-)

Oh - and for the record...when you're first starting and you don't want to have to worry about lighting and color consistency, just remove the color from the pictures before you make a .gif out of them. :-)
