It seems Lytro has a new formidable competitor in the area of light field cameras. Google revealed today that it has created a rotating arc of 16 GoPro cameras arranged vertically to experiment with light fields.
While a 360-degree camera allows you to look in different directions in virtual reality, a light field camera gives you a much more realistic sense of presence because you can move your head around in 3D space while looking in the same direction. The motion parallax and change in light experienced is much closer to what the world looks like to us in real life.
To create its light field capture camera, which captures all the different rays of light entering a volume of space, Google modified a GoPro Odyssey Jump 360-degree camera rig and bent it into a vertical arc of 16 outward-facing cameras, which was then mounted to a rotating platform.
