3D photgraphy, also known as stereo photography, is nothing new.
But while it is easy to make 3D photos, 3D viewers are still very primitive (think about those orrbile blu-red glasses or anaglyphs, or cross-eye vision ), or very expensive (like stereo projectors).
What I found was that a device for viewing 3D photos, cheap and easy to use, was still not available.
So, i made one.
Well, I hoped to make a product and be able to sell it, but at the end, I had still my prototype laying here, so let's at least make an instructable out of it :)

The basic idea is always the same: you must have two photos, two images, of an object.
One is what the left eye would see, the other is what the right eye would see.
Usually you get these two images with two cameras, or by taking a photo and sliding the camera horizontally for 6-7 cm, that is the distance from one eye to the other.
Then, you show the two images to people, managing in some way that their left eye sees only the image taken with the left camera, and their right eye sees only the image taken with the camera on the right.
If you manage to do so, no matter how, they will see a 3D image of the object you photographed.

Either monitor (what mirrored) picture is mirrored. You must mirroring this picture before, in order to see it correctly than. I use Stereoscopic Player to view my pictures or movies.
I use my computer for modeling in 3D.
I'm interested in which program can flip mirroring only one desktop when I use dual monitor.
if yoiu use crt monitors instead, then you will need a sheet over each monitor too.
The problem with LCDs is, that some have 45 deg angled polarizers and some don't. With 45 deg it works, when you flip one of the by 180 deg. With 0 oder 90 deg, you're doomed. You might consider this : 3-D iPad stand

It is spanish text, whose translation is: Finally, after much prodding, I managed to see the PES (Parallel Eyed Stereograms) using two identical magnifiers. They are about 5 diopters, and placed before the eyes so as to use only the edge nearest the nose. It's the same effect (or almost) of the legendary Holmes stereo viewer. I normally use 2.5 diopters glasses, but I had to ignore them because all together was too much magnification.
Good thing I didn't know it, it's nice to know that I arrived here just from my thoughts instead of reading it somewhere :) Maybe if I had known that it was patented,i would not even have made it:)
