By recording and processing the direction of light rays entering its sensor, the forthcoming Lytro camera promises to provide previously impossible features, such as the capability to focus on any part of a photo, at any time, or even bring an entire photo into focus at once. The camera isn’t slated for release until later in 2011, but you can play with refocusing photos and read more about the technology on Lytro’s site now (the picture gallery requires Flash on a Mac, but does work in iOS via HTML5). follow link
How Loud Are Your Mac's Fans?
When they get hot, Macs turn on various internal fans to keep components cool. The noise can be annoying, but just how loud is it? If you have an iOS device with a built-in microphone, you can download one of many free sound meter apps (search on
decibel in the App Store) and see if you're subjecting your ears to a truly unreasonable noise level.
Lytro Promises to Revolutionize Photography
Otherwise, you'll be left scratching your head for a while - like I was - wondering what the fuss is all about. :-)
