The Business of… 3D
Yes – it’s cool again. Three dimensions are spelling out big bucks for movie makers, TV manufacturers, gaming firms, and publishers, as people fall in love with 3D again.

To put it simply (which, let’s face it, is always the Kipp way) two cameras capture the same image at the same time from slightly different positions. Our brain receives the two images and correlates them into one, but the different angles produce the “depth” of 3D.
In the cinema with those ridiculous glasses, two images are projected onto one screen, one in red, one in blue. The different colored lenses mean only one image can enter each eye. It’s good for simple effects, but rubbish for a full color movie, which could explain why 3D never stuck around in its early days.
The next stage, the one that has made 3D tolerable, is polarization. It makes Kipp’s head hurt to think about it, but basically (we think) the film is projected faster – much faster – and that exposes every frame to the eye more, reducing flickering and stuttering. Combined with other advances, the result is a much more mature appearance. There are now numerous techniques to creating 3D, including some new ones that don’t require glasses for viewing.
