Lytro is going to launch a camera that takes pictures instantly and lets you focus anywhere within the frame.
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.
You don’t need to focus at all, you can adjust the focus itself to any point in the frame after you actually took the photo and comfortably sitting on your sofa.
Focusing after means no auto-focus motor. No auto-focus motor means no shutter delay (and battery saving).
It Will Cost $399 (and $499 for a more advanced version with 16GB instead of the standard 8GB).
The battery should be great, you should able to fill up the entire camera with pictures on a single charge. So about two weeks of battery time, with regular usage. An entire vacation with no charger.
In the specification you can find “Light Field Resolution”: 11 Megarays: the number of light rays captured by the light field sensor.
The light field is a core concept in imaging science, representing fundamentally more powerful data than in regular photographs. The light field fully defines how a scene appears. It is the amount of light traveling in every direction through every point in space. Conventional cameras cannot record the light field. You can get more details about that on Lytro’s website (Details section) or on Wikipedia.
Go to the Picture Gallery and play with some of the photos. It looks amazing.
This technology inevitably could be implemented in the next future to high end cameras and it would be great particularly for action photography and of course street and reportage photography as well.
A great advantage not having to think about focusing while shooting. On the other hand, there will be something left to do to for the photographer than holding a camera?
