Not Everyone's Ready for 3D

Rafe Needleman of c|net has a problem with 3D. He's a self-described "flat viewer" and thus can't see 3D effects even if they work fine for most other people. And he's not alone. Four to ten percent of the population has the same problem, "depending on which expert you ask."

"Stereo blind" is what doctors call the inability to process stereoscopic images. However, the condition can be treated with graduated lenses that act as training wheels. Eventually the eyes and brain can see 3D once the training wheels come off, just as many of us learned to ride a bike.

"Personally, I have no interest in undergoing medical treatment just so I can spend more money on consumer electronics," Needleman commented. He's happy watching 2D.

However, whether you abstain from 3D due to visual handicap or just don't like the idea, you may be missing out on the next chapter in the evolution of movies. Needleman explains: "When directors create shows for 3D, they can't rely on cinematic methods viewers are used to in 2D for conveying action, depth, and movement. Hard cuts and swooping camera moves can disorient viewers new to 3D. The new standard of practice is to lock down the camera and move the action around it, instead of the reverse, which is the case in today's 2D movies."
