It's a timeless gag by now, but one that never seems to get old. Tell your friends you're taking their picture, and have them hold some contrived pose for seconds on end while you sneakily record video. Especially if they are at a club, and have dumb glowy stuff on their faes.

As a bonus, nothing quite surfaces the artifice of 'candid' photography quite like watching these videos. Seeing these human creatures try so hard to put on their best/funniest/goofiest/coolest/ look makes seconds feel like hours. My advice for portraits? Simple natural smile or GTFO. [DiggVideo]
