A Lytro camera uses Light Field Photography (also known as plenoptic photography) which captures all the available light in a scene going in every direction. It works by breaking up the main image with a microlens over an image sensor. (Source: Wikipedia)
Engadget had hands-on experience with this Lytro camera. Check that out for more photos and videos.
Features of a plenoptic camera include:
- Refocusing: Users are able to refocus images after they are taken.
- Speed: Because there is no need to focus the lens before taking a picture, a plenoptic camera can capture images more quickly than conventional point-and-shoot digital cameras.
- Low-light sensitivity: the ability to adjust focus in post-processing allows the use of larger apertures than are feasible on conventional cameras, thus enabling photography in low-light environments without a flash.
- 3D images: since a plenoptic camera records depth information (which allows it to focus at variable depths), stereo images can be constructed in software from a single plenoptic image capture.

Now, besides this camera being cute and capable of being discreet while using in public, the Light Field Photography is a new technology to try out. Thus, this is another must-have — another gadget to buy once this officially comes out!
