This Is How Lytro Takes 'Living Pictures'

Commentary by Stephen Downes

The phrase 'living pictures' is nice marketing, but the development of light-field photography is genuinely revolutionary. The concept is actually fairly simple: where you would normally make selections when you take a photograph - you might focus on a specific object, for example - the light-field camera captures all the light available at the time, allowing you to make these selections after you've captured the image. Digital photographers make numerous selections when they take a picture - they select depth-of-field, white balance, focal point, and more. It's easy to mae a mistake (trust me). Light-field photography allows you to make the right choice later (somehow Future Shop obtained an exclusive license to sell them in Canada, and naturally they're sold out).
