The glasses for IMAX Digital 3D are larger to accommodate for the larger screens while the RealD 3D are just the standard size of 3D glasses.
The audio in the IMAX 3D is uncompressed and therefore seems to be of a better quality as opposed to RealD 3D whose specifications on sound are not standard but vary by theatre.
Is IMAX better than 3d?
There are some subtle differences between IMAX 3D and normal 3D though both are basically the same. An IMAX screen is bigger and curved, so that the image really fills your field of vision. An IMAX screen is usually about 5 stories high! Digital 3D is on a regular sized movie screen.
Do you need glasses for Imax 3d?
No glasses are required for the standard IMAX presentation (which is the RECOMMENDED way to watch movies, might I add!) It truly does add to the movie-viewing experience. Glasses are required for the IMAX 3D presentations, however.
What is the difference between IMAX and IMAX 3d?
Unique to IMAX is its huge screen, which is bigger than any other format, up to 40% larger, and it uses an aspect ratio that’s taller than other theaters. With some movies, this means you’re seeing more of the image instead of black bars on the top and bottom of the frame. Like Dolby, some theaters also offer IMAX 3D.
Are IMAX 3d movies worth it?
Digital IMAX is far less of an impressive experience, but it can still be worth it for a number of people, especially when viewing a movie in 3D. In the near future though, dual 4K laser IMAX should make the Digital IMAX experience a fair bit closer to the traditional, analog IMAX. Exciting times to be a movie goer.
