    So you're saying you CAN'T see the difference??

    Or one might also ask if the difference's worth spending much more money to
    achieve it?

    and then down sampled for the web. So in other words, zero scientific
    methods were applied to this so called "test"

    100% pixel view, as noted in the OP, and in the image itself. Notice
    the scroll bars as well.

    I assume the one on the left is the 24mp. You can especially see the
    difference in the highlights on the lips, skin texture, and the black
    speck to the right of her nostril, although there *could* be focus
    issues involved. I'd have to see the 12mp not up-rezzed.

    Plus, those are JPEGs. Let's see a side-by-side without JPEG
    artifacts.

    you're right.
    you /can/ just see the difference - if you look very hard at 100% view.

    Why does anyone posting in the english language assume that an inanimate
    object could have a gender?

    You're absolutely right - it's slightly more than nothing at all.

    It would be the differance between scanning film at 2000 ppi vs 1420,
    is this a large differance?

    If the camera is used with really good lenses then you can make a
    12x18 inch print from the 24MP camera that is just as sharp as a
    8.5x12.75 inch print from the 12MP camera, is this worth that little?

    The differance might not be a knock you socks off kind of thing, but I
    would not dismiss a gain of resolution of that level.

    Of course you mean double the pixels/inch, so 4 times the number of
    pixels.

    I am almost 3 steeps ahead of you, 96 MP is a very small image for me
    when stitching a photo, almost a snapshot size, 384 MP is about the
    average size I get when stitching, and 1,536 MP is just a bit past
    what I have don't, so far maxing out at 1,1000 MP.

    This should be on alt.urban.legend...

    You can get excellent 12x18" prints from a 6 mp dSLR. IMHO people should put
    their calculators away and take photos. Only the marketers and measurbators
    care.

    Mostly I try to keep the both dimensions below 25,000, otherwise I
    can’t make a jpeg of it. Past 30,000 and I can’t edit it with
    PhotoShop Elements.

    But of late I have started taking a lot larger pan, mostly because I
    now have a Gigapan unit. My largest on is 83,985, 13,631, which can
    be seen here
    http://gigapan.org/viewGigapan.php?id=8682

    I think I will mostly be doing 200-600 MP images, over 1 GP and they
    get somewhat slow to stitch.

    This is about as small as I make them, at least while I am playing
    with the Gigapan.
    http://gigapan.org/viewGigapan.php?id=8838

    That one is only 17,584, 9314.

    Here is one of Coconut Island, on the Hilo side of Hawaii.
    http://gigapan.org/viewGigapan.php?id=6845

    A little more interesting that the others. I really want to redo that
    one at much higher resolution.

    You can make a decent looking 12x18 print, but if you make the same
    print from a 12 MP image it is going to look sharper. T0 get a super
    sharp print you need more like 35 MP, 400ppi, but you have to look
    pretty close at the print to tell the differance between 300ppi and
    400ppi.

    Hair in the 24mp shows more finer detail too but it is not a big enough
    difference to warrant a new camera with 24mp. Not for me anyway. Maybe 50mp
    is when I will get a new DSLR.

    Depends on how you intend to display the photos. If you want large prints
    for art gallery display then it may be worth it.
