The Lytro is a revolutionary new camera that doesn't need you to fiddle around with stuff like focus, zooming, focal points or any other such settings. Instead, it takes in a boatload of information and then lets you tweak it after the fact.
It's sort of difficult to wrap your head around what this means. The easiest way is to play around with a demo photograph yourself, one of which is below. Prepare to have your mind blown.
The best part about the technology is that it doesn't create insanely large files as one would expect. The creator of the tech, Dr. Ren Ng, claims that the files produced are about the size of an average digital photo today, with all the hard work being done by the camera's processor.
It's a technology that has the potential to completely revolutionize photography. Imagine having this sort of camera built into your cellphone? It might not be all that far off. We could see a dedicated Lytro camera by the end of this year, even.
