Sigma/Foveon change their tune (great technical article)

  1. Well then, you secretly are. Point being, your claim that 3 chip cameras
    only have one chip is obviously silly.

    Stop lying, I never claimed that. You ovbviously have no reading
    skills. YOU claimed the SD9 was a 3 chip fabbed as 1 chip...that makes
    you the only person here STUPID enough to claim that. Only in your
    world does 3 = 1...

  3. Obviously. And why is any 3 chip camera no better than a 1 chip camera,
    IYO?

  4. The point is Foveon measures color. Bayer guesses color.

    I never mentioned a 3 chip camera at all until you accused me of
    thinking a 3 chip camera had 1 chip (which I never did, last I looked
    3 = 3). AFAIK, there are no consumer available 3 chip still cameras.
    Your "3 chip fabbed as 1" SD9, from the pictures I've seen, is most
    certainly no better than a comparable 1 chip camera. The color's are
    awful, objects have odd textures (ie, wax trees, plastic rocks), etc.
    As I've said before, if Foveon can overcome the problems with the
    sensor, they will have something...until then it's just a interesting
    toy.

  6. You never mentioned Foveon??

    You do realize that Foveon was once the world's premiere 3 chip sensor
    manufacturer until they discovered they could fab all 3 chips together on a
    single chip, right?
    So the question remains, does a 3 chip camera have 3 chips, or 1 chip,
    IY"O"?

    you're not even understanding what you preach

    are you on dope ? where does it speak of 3 chips ?
    you seem even unable to understand what you read ? BTW can you read ?

    Like I said, you brought up 3 chip cameras....
    If we were discussing video cameras I might care, we're not....so I
    don't. We are discussing still cameras, none of which currently (that
    I know of) use a 3 sensor/chip arrangement.
    Learn to read George, I answered you 3 times already...3 chips is 3
    chips, not "fabbed as 1"

    Bayer interpolates color from neighboring pixels. In the case of a
    camera like the 10D, the data it is interpolating with is extremely
    accurate, so the average color of any 2*2 or greater pixel area is also
    extremely accurate. Foveon measures full RGB at every pixel, but
    doesn't do it well, and is not very accurate at any scale.

  10. That's because of the Pro 10M, Foveon used to make 3 color stills. They've
    moved on to DSLR 3 chip sensors, fabbed as one.
    IOWs, you continue to insist, 3 chip cameras only have 1 chip.
     
    George Preddy, Dec 19, 2003
  11. Ahhh, that color data was already used in other pixels already--what a total
    mess, no wonder they are so blurry and artifact ridden.

    Not even foveon claims this, only YOU...
    Like I said, your SD9 has 1 chip...your SD9 is not a 3 chip camera,
    only YOU claim this
     
    Bill M, Dec 19, 2003
  13. But you do insist there is no advantage whatsoever to using a 3 chip camera
    over using a 1 chip camera.

    Por choice, really, as "interpolates" is more accurate and doesn't imply
    the randomness that "guesses" does.
    Wow, you've learned absolutely nothing!

    First of all, "artifact" means that something is there in the image that
    really should't be there. A lack of resolution is not an "artifact".
    If there were green pixels in a purple flower, *that* would be an
    artifact. By your definition, everything we capture is an artifact,
    because all cameras could be sharper and have higher resolution. You
    are illogical.

    And you twist and lie with every post...never said that either...
     
    Bill M, Dec 19, 2003
  16. So now you agree than 3 layers is better than 1.

    I agree you like to put words in other people's mouths. In the case of
    the SD9, 3 layers are not better than 1. Capturing full RGB at each
    pixel will be better than 1 when someone gets it right...heck,
    capturing more than 3 colors per pixel would be even better. Right
    now, it isn't happening...

    Maybe he's "measuring" colour with that ruler he posted in his "Penny
    Challenge". You know, the one with 9mm per cm.
     
    Chris Brown, Dec 23, 2003
  19. The 10D can't resove any mm marks.
     
    George Preddy, Dec 23, 2003
  20. Ahhhh, so it's because you hate the companies involved that you claim 3
    layers are only 1 layer.
