RealD vs. Imax Digital 3D: What's the difference?
CNET.com (Asia) hopes to answer the question…
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? Here what we know.
