There's been a ton of speculation about the HTC One M8's strange new camera. With one large lens on the back and a slightly smaller one just above it, no one quite knew what to think. Is it just a 3D camera? Is one telephoto and one wide? Is it a light field camera like the Lytro? None of the above.
Turns out, it's actually something entirely new (to mobile phones, anyway). And it could be a glimpse at the future of photography.
