Interesting. A viewpoint of the maker of 3D movies.
My father was a 3d photographer: Leica-3d-adapter, Verascope, Viewmaster, etc. He never adapted the red/green technic, he worked with either double slideviewers or a polafilter-projector.
The stereo effect was clearly visible, also for the family. But it stayed in the state of an effect, a demonstration of an optical illusion.
I have always suspected the difficult height standardization of the 2 slides as the cause of (light) headaches. But the argument in the article is, that it is a structural problem.
I like some 3D and really enjoyed seeing Avatar in 3D, for example. I probably see 1-2 movies in 3D per year, and I generally pay the big bucks to travel to San Francisco to do it.
Hubble 3D and Sun 3D (both were awesome, but there was a parallax problem with the Sun 3D for reasons explained here)
Avatar (again; we saw it in 3D twice)
Despicable Me (on my birthday because that's when it came out)
Anyhow, no plans to see anything in 3D this year unless it's shot in 3D. Thor, perhaps.
