Question: what is the difference between 2d and 3d imax?
Answer: The only difference between IMAX 2D and IMAX 3D is, well, whether it's in 2D or 3D, that is, whether it's “flat” or provides the illusion of depth. ... IMAX Digital was introduced in 2008 and uses two aligned digital projectors at 2K resolution, which, for practical purposes, is 1080p HD with a bit of extra width.
