The point is that the more photons you capture, the less noise you get. Assuming the Foveon wastes the same percentage of its area on interconnect as a Bayer pattern chip, the Bayer chip will filter out all the "wrong" color photons that hit each sensor, while the Foveon will actually use them. Obviously, implementation matters. But I see no reason to expect that a Bayer pattern chip is intrinsically better--it's just been worked on longer. -- Ciao, Paul D.
