  5. Hey George - how about some Christmas lights shots with the SD9? Should
    be a good test of resolving power, with the small points of pure red,
    green, and other color lights.

    under a blue sky which it reflects thus making the clear water look
    blue.

  7. It is titanium, and it is blue.

    Neither Mare Tranquillitatis nor the moon's sky are titanium.

  10. I'm using a 35mm standard for the SD9 focal length too.
    x 1.6 for the crop factor
    I've yet to see a D60/10D Moon shot that has proper color. If you know of
    one please link it.

  11. The area is titanium rich, which gives it its color.

  12. The SD9 can image the titanium rich soil, uhm, dirt, uhm, dust, uhm, sand,
    uhm, stuff on the surface. The D60 can hardly see the Moon itself.

  14. But he answers all the guys that are criticizing him and his camera - I
    have been somewhat on his side and trying to help him. In this thread, I
    suggested a type of photo that might show the SD9 to advantage. In a
    previous thread, I made a long, sincere post trying to understand where
    he was coming from, and suggesting ways we could judge how good some of
    our cameras are. It deserved some sort of comment, or at least a
    courtesy reply, but nothing.

  15. Only in SD9-land is right. Here is an enhanced color image of the Moon from
    Galileo, blues and reds are enhancements of very subtle shading in the
    visible spectrum. Match it to my Foveon image below, it is a perfect
    match...

    Foveon is absolutely stunning. What could be a more amazing demonstration
    of this unbelievable sensor? It quite literally blows Canon off the face
    of the Earth.

  16. "As a result, the red and blue intensities are controlled by visible color"
    I know it is hard for you to accept the SD9 is this far superior to
    everything else on the market, especially after claiming that the Moon is
    colorless and the Foveon lack of color interpolation invented false colors,
    but you need to learn to live with it. The color not faked as you claim,
    which now seems to be your last line of defense, Canon/Nikon/Fuji are simply
    that far behind.

  17. The reds and blues in the Galileo image are enhanced from the visible
    spectrum, greens however show depth. Here are the two images side by side,
    the Sigma SD9 image has been color saturated to 100% using Photoshop,
    nothing else was done to it. The yellows/whites are washed out reds/blues
    due to the obvious difference in Moon phase...

    He wouldn't respond to me when I was looking for SD9 raw images to examine
    the actual sensor response, compared to the SPP processed versions either.
    The guys on the dpreview forums were considerably more helpful, but Preddy
    doesn't actually seem to want to engage anyone at all - he just asserts
    things. Even his posts that look like responses to critical posts aren't
    actually responses, becuase he seldom/never addresses actual points that are
    made, just repeats his assertions.

    It's like he thinks he's fighting some kind of fire. Any subthread that
    ends in a post that suggests the SD9 may not be the greatest leap forward in
    photography since the development of the lens, or where some other DSLR is
    being recommended, is a new piece of the fire that needs a bucket of sand
    dumping in front of it, in the way of one of his penny/colour chart/light
    bulb pictures, and a comment from his list of platitudes, "10 is better than
    6", "Bayer throws away 25% green", "Four legs good", etc.

    Said bucket of sand being dumped, the job is done and he can move on to the
    next one. Other than that, and occasionally opening a new front (when he has
    some new link or platitude to add to his collection and share with the
    world, I guess), he doesn't do anything else in here. If you're do actually
    manage to get him to engage you *and the points you're making*, it will be
    an achievement, as he's yet to actually engage anything that's put to him,
    AFAICS.

    Good luck, but I suspect you're wasting your time.

    Or is the moon made of bleu cheese?

  20. It's just that I consider this whole mess still an open question, and I
    would like to know if the Foveon technology really is superior, with its
    better color resolution, or if luma resolution is all that really
    matters in 99% of all pictures. I know the 3-chip cameras are way
    superior in video, and this seems to be a similar situation.

    I think the bottom line is Phil's resolution and noise tests, but if
    George can come up with some shots that the Bayers aren't capable of, I
    would be interested. We have already seen the color resolution charts,
    which are fairly interesting, but does that apply to the real world? Who
    knows, there may be a set of subjects, like a design of red graphics on
    a black background, or some tweed suit, or some Christmas lights
    display, that only the Foveon can resolve. I haven't seen such a
    situation with my Oly E20 yet, but it is on George's shoulders to show
    us some.

    I asked someone once to show me a good example of the "jaggies" that
    everyone says are in the Foveon images, from the anti-aliasing, but no
    response. Nor any response from George, natch.

    Detached observer,
