Lytro aims to revolutionize the entire photography industry by making the first camera to ever capture the entire light field of a photo.
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 – it’s all the light rays in a scene. Conventional cameras cannot record the light field.
Conventional cameras will require you to focus on a specific point before taking a shot. Then, they capture the all the lighting for that focused area and count it as one source of light. Capturing the entire light field will enable you to do the shooting first and focus after. This way, you won’t miss a shot by fighting with dials and settings and modes. Simply shoot and not worry about if the photo is out of focus.
The way we communicate visually is evolving rapidly, and people’s expectations are changing in lockstep. Light field cameras offer astonishing capabilities. They allow both the picture taker and the viewer to focus pictures after they’re snapped, shift their perspective of the scene, and even switch seamlessly between 2D and 3D views. With these amazing capabilities, pictures become immersive, interactive visual stories that were never before possible – they become living pictures.
Another feature worth mentioning is that the camera is said to take photos from sleep to snap in under a second. Almost no shutter lag.
