How It's Used

“‘It’s a wonder, isn’t it?’ the producer Jerry Bruckheimer asked rhetorically, looking up at a three-story reconstruction of the ship the Black Pearl on the set of ‘Pirates of the Caribbean: At World’s End.’
“He wasn’t talking about the three-masted square rigger, or even the 1,400 ceiling lights, which became so hot one day during filming some burst into flames. Nor was he referring to the 60-foot-high blue screen wrapped around the ship like a shower curtain hung from an oversized rail. What was a wonder, Mr. Bruckheimer mused one recent afternoon, was that the sequels to the first successful ‘Pirates’ movie were made at all.”

"...you can now use a photo or a movie as a backdrop when you're videoconferencing—like a bluescreen effect but without the bluescreen."

—David Pogue. Mac OS X Leopard:  The Missing Manual.  (Sebastopol, CA:  O’Reilly Media, Inc., 2007), p. 3.
