  2. They've already tried sensors dedicated to the primary colors and it
    worked poorly (Sigma).

    Bad implementation? Colours are more accurately represented by
    using RGB filters and a monochromatic CCD, individual exposures
    combined together. It's not really a debate.

  4. Scanning backs (= current, not really future) are useless for
    non-stationary subjects and for variable lighting.

  5. Here are some images which show that for Rich's education.

    I dunno, I've been kind of impressed with the Foveon sensor's color
    rendition & saturation.

    Every pixel location on the Foveon has 3 pixels stacked blue, green,
    red, just like film emulsions.

    If I didn't have such an investement in Pentax glass ...

    I really wish Pentax or Nikon would adopt that sensor. Pentax for the
    glass I've got or Nikon to make it worth switching over.

    Actually, what I'd like to see is a full frame size sensor maintaining
    the current pixel pitch. That'd give an effective 31 Mp sensor (3944
    columns X 2629 rows X 3 layers) that recorded pretty much like film.

    That wouldn't be such a bad thing.

    In message <8NGZe.71787$>,
    The Foveon's sensor has almost no saturation at all. The saturation you
    see in the images comes from software interpolation, and the hue noise
    can be pretty strong in the blue/green area. In fact, in sea and in sky
    you can see little blotches of greener and more magenta blues. This is
    especially true in shadows; in an image of a grey stone bridge that
    someone linked to here a while back, there were big color blotches when
    the stones were boosted in illumination.

    With what is *your* sensor saturated? Green thee? Whats this mumbling
    about saturation coming from software? Whats this got to do with hue
    noise? How do you boost your stones (or someone elses stone) in

    Big load of bullshit.

    I understand what you're saying, but I just don't see it looking at the
