Once again, Herzog is my man:

And my hero, Werner Herzog, is using 3-D to film prehistoric cave paintings in France, to better show off the concavities of the ancient caves. He told me that nothing will "approach" the audience, and his film will stay behind the plane of the screen. In other words, nothing will hurtle at the audience, and 3-D will allow us the illusion of being able to occupy the space with the paintings and look into them, experiencing them as a prehistoric artist standing in the cavern might have.

That sounds awesome.

Even though it was great fun watching Avatar in IMAX and in 3D, I can't help but cringe at all the wasted plastic used for the glasses.



There are several competing theatrical 3D systems: RealD, Dolby 3D, XpanD. Their technologies are completely different: respectively polarisation, wavelength multiplexing, shutter glasses.

Only RealD uses cheap disposable glasses. In Dolby 3D and XpanD, the glasses are fairly expensive to produce, and thus are recycled (collected from the audience after the show, washed and redistributed).

Americans seem to overwhelmingly prefer RealD, while Dolby 3D and XpanD dominate in Europe. Anyone surprised? :)


In Italy Dolby 3D is the only one I saw used. You get the glasses when entering inside the cinema, (they are washed with a special disinfectant in order to kill viruses and other bugs), and then after the show you give it back to the cinema guy.

It's fun the first two times, just to try, but the plain cinema is much better, with better colors and a lot more relaxing. The good thing is that since the 3D mania there are no problems in fining available sits in the non-3D rooms.


Really? They ask you to turn the RealD glasses back in at the theaters I go to.

We don't actually have any options in the way of 3D movie technology.
