The technique for 3D Stereograms is just the opposite it seems for these pics. The 3D SG's you relax your eyes, and focus as if the picture was much farther away from you. And the images meet in the middle that way. With the pics linked to in this thread, you have to force, or cross your eyes to get the images to overlap, at least that's what it seems like to me.

Very cool, seen stuff like this before but it becomes a lot harder the bigger the image gets.

also, can anyone clearly explain why the 3d image appears smaller than the 2 originals? is your brain tricking itself?

How do you "straightening your eyes"? Isnt it already straight??

not really. the closer an object is that you're focusing on, the less "parallel" your eyes are. think about am isoceles(sp?) triangle. your two eys at the base and the center of you vision (focus) at the apex. you get two slightly different perspectives because your eyes are small distance apart. your brain puts these two images together and that is what makes objects look "3-d".

this photo probably used two cameras about as far apart as your eyes, but both focused on the same point. by retraining your eyes you put the two images together as though you are looking at one real object. The brain then sees the image as it would if it were viewing the real object or woman in this case.

same sort of technique has been used in video games. the card switches between two slighty spaced perspectives in the game. special glasses sync the frames with what each eye is allowed to see. people that can't see this image would see this technique because the special glasses do the work for you.

its easier to cross your eyes if you put your finger infront of your face and focus on it. Then adjust the distance of your finger between your nose and the picture till you can see 3 pics next to each other behind your finger. Then keep focusing till the image stops moving and you're there. Eventually, you can remove your finger and view the whole image.

This is so 1990.
...

It's cool, don't get me wrong, but I remember doing this sort of thing in 3rd grade. And I'm 22.
