CNN uses “hologram” effect in election coverage

In the CNN election coverage last night, November 4, 2008, Wolf Blitzer and Anderson Cooper were seen talking to life-sized holograms resembling the hologram of Carrie Fisher as Princess Leia in the film Star Wars.

The holograms were produced, as the Baltimore Sun reports, by pointing 35 HD cameras at each subject during the interview; green screen-style technology was then used to superimpose a three-dimensional image in a predetermined location in the studio.

The holograms were not actually visible in the studio.

I liked the effect, though really it’s something of a gimmick.  One practical side-effect of the process was that the background noise was filtered out, so that Will.i.am who was in Grant Park, Chicago was heard clearly despite the surrounding chatter.
