Two cameras, two magazines, two opposed opinions

    Magazine 1: "The D200 has less noise at high ISOs than the 30D."
    Magazine 2: "The 30D has less noise at high ISOs than the D200."

    I've seen identical scenes shot with both cameras. The D200 definitely
    has more
    (and different and IMO, worse noise) than the 30D at 1600 ISO.

    So how can magazines come to such opposing opinions?

    It's not like there is much variation from one camera to the next from
    the same
    line.

    Check to see which camera manufacturer provides them with the most ad
    revenue.

    Shocking isn't it? Everything you read may not be true!
    Unless it comes from the White House . . .

    That's fine for a story where opinion can make up the bulk, but camera
    noise is testable and the tests if done correctly don't lie or deviate.

    Shocking. Two different people with different opinions? What is the
    world coming to?

    My thoughts exactly.

    Go into a camera shop with you CF and takes shots with both of similar
    subjects at ISO 1600. Take them home and examine closely.

    In other words, don't take someone else's word for it!

  10. So, when someone's saying that 2+5 equals 5, and someone else is saying that
    it's 4, do you see it as just two different people with different opinions?

    If it was that simple, the answer would be obvious: they are both
    wrong. Actually, in this case, that is probably exactly the case.

    Noise comparisons are difficult. It is easy to make a noisy picture
    with any camera and then claim that it is noisier than some other
    model. Some cameras do more in-camera processing (even on supposedly
    RAW files) than other cameras, too, so a direct comparison is
    impossible.

    It is a trade-off. Generally, the more noise reduction you do on a
    picture, the less detail it will have, whether that noise reduction is
    done in the camera or in editing. The D200 and the 30D both have
    several user adjustments for noise reduction, but they both also do
    some noise processing even with all these adjustments turned off.

    So no, there is no objective measurement that tells you that one camera
    is noisier than another.
