Lytro lets you take pictures like never before. Unlike a conventional camera that captures a single plane of light, the Lytro camera captures the entire light field, which is all the light traveling in every direction in every point in space.
Capture living pictures with the press of a single button. By instantly capturing complete light field data, the Lytro gives you capabilities you’ve never had in a regular camera.
Since you’ll capture the color, intensity, and direction of all the light, you can experience the first major light field capability – focusing after the fact. Focus and re-focus, anywhere in the picture. You can refocus your pictures at anytime, after the fact.
And focusing after the fact, means no auto-focus motor. No auto-focus motor means no shutter delay. So, capture the moment you meant to capture not the one a shutter-delayed camera captured for you.
