Always on cameras  AUG 14 2009

Adam Lisagor notices that the iPhone 3GS camera might always be buffering images so that when you press that shutter button, you get the photo that you wanted, not the one delayed by slow software or a slow shutter.

In order to get the jaw-dropping slow-motion footage of great white sharks jumping out of the ocean, the filmmakers for Planet Earth used a high-speed camera with continuous buffering...that is, the camera only kept a few seconds of video at a time and dumped the rest. When the shark jumped, the cameraman would push a button to save the buffer.
