Very interesting question Skye.
I have talked about that subject with a friend of mine. He told me that he knows a guy that works with him that only sees with one eye...and he has trouble with distances and depth (he was born seeing with one eye only). That points to think that he only sees kind of flat images.
But some people who were born with both eyes and then lost one, they can somehow see still a 3-D world...probably their brains has "storage" previous information for them to use later, even with one eye.
It's a complicated subject.
For 3-D Digital Cinema and most T
