The right side image will show the same displacements to the left. When these images are properly dislayed and viewed from the right distance with both eyes, the impression is a three dimensional view from a flat representation.

    There is no cropping or computer manipulation of a single image that I know of that will replicate that.

    Can someone chime in here with some theory or formulae to make me seem like I really know this stuff? Working with one eye pretty much blind and the other corrected to 20/200 here.
    True, Drew. I was thinking, but failed to write, that I have a vague recollection of doing something like that with the images swapped left-for-right to create a "false stereo effect". My memory, though is vague and I don't have the time or interest in doing the homework on it. Well, really I have interest... just no time to do anything more than write this post.

    i use an old polaroid / land portrait camera do do this.
    i've never tried using tilts and swings to do this, just moving
    the camera a little bit
    or using a camea with 2 lenses on it.

    not sure if you found this website drew: http://www.stereoscopy.com
    there are a few others out there dedicated to 3d "stuff"

    good luck !
