Shoot now, focus later camera unveiled

Huffington Post.

Lytro, a Silicon Valley start-up, has unveiled a camera that lets users focus a picture after they take it, over and over again.

According to ABC News, the camera uses what is called light-field technology, which, rather than taking in the usual snapshot of light hitting a sensor, separates rays of light so as to record their individual characteristics.

That way, it is possible to alter the focus afterwards to create what Lytro founder and CEO Ren Ng says is a “more powerful photograph.”

USA Today reports that although the camera itself is not due out until late 2011, Lytro last week unveiled a carousel of demonstration snapshots, all of them embeddable, available in Flash for the Web and HTML5 for smartphones.
