“The network won’t divulge the cost of the technology, which allowed Wolf Blitzer to speak to what viewers saw as a flickering image of correspondent Jessica Yellin, who was in Chicago. (An even more weird moment came when CNN’s Anderson Cooper interviewed musician will.i.am from Black Eyed Peas via hologram — or was it hol.o.gram?)”
“To create the image, CNN used 40 cameras to film Yellin, a green-screen environment inside a specially constructed tent, a TV screen that allowed Yellin to see the combined image of her and Blitzer, a set of computers that made Yellin’s image camera-ready, and “a mix of mechanical and infrared camera-tracking technology to create a realistic holographic image,” according to CNN spokeswoman Erica Puntel.”
