Sometimes, taking photographs can be frustrating especially if you can't get the right focus. Worry no more because there's a new and revolutionary camera that allows you to change the focal point after you have shot the photo.

It's called Lytro - a light, funky looking camera that has a unique 'focus' function. If the predictions are right, then this new camera technology will change photography forever. For backpackers and travelers, this gadget will come in handy especially for those who are always on-the-go. Landscape, sports or any action photography for that matter, can be now be shot effectively without giving a ton of thought about how it will turn out.



But how does this camera set apart from other cameras available on the market nowadays?  For starters, Lytro can capture all of the light in a scene more than a regular camera can. In a regular camera, you need a bunch of cameras tethered to a supercomputer to capture all the light needed. Lytro has a light field sensor that collects color, intensity and direction, capturing all the light rays in the scene.

Design-wise, it's weird looking but in a cool way. It's the camera’s 8x optical zoom lens that inspired the design.  The body is made of anodized aluminum that makes it pretty light but sturdy allowing users to take it anywhere for capturing important and interesting moments. With its instant shutter, no time will be wasted anymore on focusing to achieve a perfect shot. What's more, the picture-taking process is incredibly quick because of its instant power on.

Lytro features a software responsible for developing 'living pictures' - you just need to plug your Lytro light field camera into your Mac then you can manipulate them and share online and via social media. Lytro uses a rechargeable lithium ion battery, which you can connect via a USB port.

The drawback is right now, the software only works in Mac. Windows application is not available until 2012.

Price ranges from $399 (8G) to $499 (16G).
