3D movies

Watching 3D movies was a great experience for me. I’ve watched once and I was amazed by how they can convert something on screen and make us feel like we are in the scene too with them. And it all because of the glasses and technology that that’s in the movie. Long before movies like Hobbit were shot and viewed in 3D, people were putting on real live performances, which don’t simply approximate the 3D experience – they are the genuine article.

3D movies are quite common these days, with many of the latest animated films, action-packed blockbusters and horror flicks being presented with a third-dimension. The passive polarizing technology used to display 3D in most movie theaters is also similar to those found in passive 3D TVs. However, the fact that some movies are presented in several 3D formats in the theaters can be somewhat confusing.
Most of us who've caught a 3D movie at the cinemas recently probably experienced the more common RealD 3D technology, while Imax Digital 3D (as well as its analog counterpart) is a format presented at Imax auditoriums. But is there any difference between RealD 3D and Imax Digital 3D?
Why do people like 3D movies? If people are all 3D-ed out in their regular lives, why do we jump at the chance to wear funny glasses at the cinema? Part of the attraction, surely, is that movies can show us places we’ve never been, whether real or imaginary, and so with 3D we can more fully experience what it is like to have a Tyrannosaurus rex make a snout-reaching grab for us. But there is more to it.
3D movies differ from their real-life versions because everyone in the audience is a target, and all at the same time. This is because the 3D technology (sending up left and right eye images to the screen, with glasses designed to let each eye see only the image intended for it) gives everyone in the audience the same 3D effect. These passive 3D glasses use polarizing filters to allow each eye to see a slightly different image. This is why the glasses can sometimes seem darker in one eye than the other--it's meant to block out certain spectrums of light. The glasses at Imax theaters are larger, to compensate for the larger field-of-view at those auditoriums.

Both these technologies are also digital, which means that you'll get a clean image and none of the image noise or "cigarette burns" that are visible from regular film projectors.If the dragon’s flames appear to me to nearly singe my hair but spare everyone else’s, your experience at the other side of the theater is that the dragon’s flames nearly singe your hair and spare everyone else’s, including mine. If I experience a golf ball shooting over the audience to my left, then the audience to my left also experiences the golf ball going over their left. 3D movies  put on a show that is inextricably tied to each listener. It invades each listener’s space. Everyone’s experience is identical in the sense that they’re all treated to the same visual and auditory vantage point, but everyone’s experience is unique because each experiences themselves as the target. Each believes they have a special targeted vantage point.
The difference, then, between a live show seen up close and a 3D movie of the same show is that the former pulls just one or several audience members into the thick of the story, whereas 3D movies have this effect on everyone. So part of the fun of these movies is not they are 3D: the fun is in being targeted. And that fundamentally alters the emotional experience. It no longer feels like a story about others, but becomes a

story that invades your space – perhaps threateningly, perhaps provocatively, perhaps joyously.
No, we don’t suffer the indignity of 3D glasses for the “popping-out feeling”. We enjoy 3D movies because when we watch them we are no longer mere audience members at all.
