(I'm liveblogging from TED 2008
, in Monterey, CA. This morning's session is "How Do We Create?")
Presenter: John Knoll, inventor of Photoshop and visual effects supervisor at Industrial Light and Magic.
John compared how visual effects were made for movies from the 1950s with contemporary movies. He showed clips from Disney's 20,000 Leagues Under the Sea and clips from Pirates of the Caribbean.
The process hasn't changed that much. You start off looking at the script, have discussions with director, and decide what needs to be shot using visual effects: anything you can't just go out and shoot, anything that doesn't exist, anything that's too expensive, too dangerous, or just not possible.
20,000 Leagues Under the Sea used miniature ships in a studio tank (about 200 ' x 200', a few feet deep). The last pictures that used this techniques was Tora! Tora! Tora!. The tank method works pretty well but the scale of the water doesn't work well. Droplet size is wrong.
For Pirates, Knoll also built a tank, but came up with ways to split in full-size water droplets. Adding full scale water in background really helps.

Even the most expensive pair of hi-fi headphones can’t match the feeling of bass rumbling through your body at a live show. That’s why music aficionados designed The Basslet, an accessory that reproduces that sensation from your wrist. Does it make your whole body shake with deep subs? Not really, because that would be terrifying, but […]

Thinking of a business idea is the easy part. Doesn’t even have to be a “good” idea, you can still get people to throw money at a non-existent venture, but to do that you need to at least have something even resembling a viable business plan. Why doesn’t anyone do it then? Because building that semi-viable […]
