I still go back to it and read some sections as I think of this or that idea. While stereo vision through binoculars is very similar to 3D photography and 3D cinema, it is not exactly the same. There are some fundamental differences: In 3D cinema, there is one [flat] image screen and there is no eyepiece. In 3D photography there are two screens and (usually) there are two eyepieces too. So, 3D photography is closer to viewing through binoculars. Yet 3D photography is not exactly analogues to viewing an object through binoculars either.  One key difference is that in viewing through binoculars, the light rays coming out of the eyepiece are coherently coupled with those entering the objective. This is not the case in 3D photography so primary aberrations caused by the objective cannot be corrected by the eyepiece. What are other key differences?</blockquote>
