The world seems to have gone 3D mad with films like Avitar, 3D TVs, 3D laptops, etc; fair enough you may think but what is this 3D they are talking about ?
Well it’s not 3D at all. What they are all talking about is a stereoscopic effect where two different images in two dimensions presented to different eyes give the impression of a three dimensional scene. Just film a scene with two different cameras a little distance apart and you too can produce an illusion of three dimensions. But walk around the back of Scarlett Johansson or Brad Pitt and you will soon see why it is not 3D at all.
That is not to say it is bad – just deceptively named. Call it “stereoscopic” and I’ll be happy.
