Greenscreens are Everywhere

This gorgeously-produced clip shows reality vs what we see on TV.  I knew greenscreens (chromakey) are prevalent in film, but I didn’t realize just how prevalent they are on TV as well, even for seemingly mundane scenes.  It’s reasonable for explosions and other scenes that would be expensive or difficult to reproduce in real life, but it would appear they get used all the time even to show people just walking down the street.  Cool stuff.  (via Boingboing)
