Lytro Light-field Camera

The tiny Lytro camera may not look like much, but some people say it's a photography revolution. The small, rectangular device is a digital camera that photographs the entire field of light around an object.

This means two things: First, the Lytro doesn't need to focus before it takes a photo. Second, the image can be edited and focused and refocused over and over again using special software. Almost every pixel of the image is in focus, so the user can choose what part they want to highlight [source: PC Mag].

The Lytro was just recently announced, and it won't be delivered until early 2012. But it's a great idea for the husband, dad, brother or boyfriend who's also a shutterbug. The Lytro's ability to take "living pictures" represents an amazing step forward in the field of photography.
