    These images are from Charleston SC - the Circular Church and a tourist buggy.

    Only the M Monochrom (okay, and a Foveon) can handle the edges in that first shot! Alias max.

    Now there's an idea - if the Foveon guys (or Sigma) were thinking about producing their own b&w sensor and camera, would there be any point to it - could they take advantage of all the pixels the way the MM supposedly does?

    Different colors of light are absorbed at different depths of a silicon sensor. The Foveon sensor makes use of this property to measure the values of light in layers, and use an algorithn to back-out the RGB values.

    What the Foveon sensor can do- emulate the use of color filters in producing a monochrome image in post-processing without giving up spatial resolution.

    The downside of the Foveon sensor: deep pixels, and ISO performance. It would be poorly suited for RF type lenses with short back-focus.

    The worst part of the Foveon sensor: Sigma owns it, and uses it only in their cameras.
