    Kodak’s B&W photodiode could be a nice addition to the bayer mosaic. Being much more sensitive to light It should give us better dynamic range and higher ISO at the expense of color resolution. If that is a good trade or not remain to be seen.
    I would love to have an all B&W DSLR, and could even use my old color separation filters occasionally, though I admit it would be a niche market for sure.
    I really hope we don’t end up with gigapixel cameras with so much noise that the camera’s denoising makes it look like photoshop’s paint daubs filter was applied to the image.

    hmm… 1.4┬Ám pixels.
    Though smaller pixels have better detail capability, they are easily swamped and lead to bloom. The sensor, by today’s commercial technology, would have less color fidelity and less quantum efficiency. However, that gives it a natural boost in low light situations, so long as the noise can be well controlled.
    I’ll be very interested to see how they solve these issues, as microscopy cameras could really use a boost in this area.
    The engadget article also mentions a 4th “layer” of pixels… afaik, only the Foveon sensor uses Si as a frequency filter in a layered configuration. Almost everyone else uses a standard Bayer mask (except Fuji’s hex pattern), with a GRBG pattern. Do they mean to say one of the green pixels is being replaced with an unfiltered pixel?
