I felt the same way in the Imax. And to provide some context to my downvoting detractor, here's what I was using as the basis for my speculation: http://news.ycombinator.com/item?id=995096 http://news.ycombinator.com/item?id=995096 It's a huge comment, so here's the relevant bit: "What Cameron has been doing with Avatar is to shoot in deep focus (no using the aperture and focus controls to blur out the background, a favorite technique for isolating the subject from the environment) but instead create depth by altering the angle between the two lenses dynamically, creating the illusion of a large space in which attention to depth is focused stereoscopically. Until now most 3d projects have kept the stereoscopic distance fixed, which yields the feeling of watching the story take place on a stage in front of one and occasionally having one of the props or actors protrude outwards toward the audience. By varying the angle between the lenses in the same fashion as our eyes, Cameron presents a far more immersive way of experiencing the third dimension."
