3D in Theaters
Filed under 3D, Gadgets, Movies
There are multiple ways to do 3D in movie theaters. My favorite is RealD because of the image quality and the potential of getting normal sunglasses that work in a theater. I saw Avatar in both RealD and Dolby 3D and could not tell a difference…both looked great.
Here’s a table to help keep it straight:
Company
| Company | Technology | # of Theaters | Cost of Glasses | Can tilt head | Notes |
| RealD | Circular Polarization (passive) | 5,000 | $0.65 | Yes |
|
| Dolby 3D | Color Filter (passive) | 2,200 | $28 | Yes |
|
| XpanD | LCD Shutter (active) | 2,000 | $50 | Yes |
|
IMAX 3D uses either linear polarization (which means you *cannot* tilt your head), or LCD shutter glasses, depending on theater.
My biggest issues are…
- Letting you tilt your head during a movie
- Headaches from LCD shutter glasses
For now, I’m avoiding XpandD and IMAX 3D for 3D movies.
Much of this info is from this article.
