Something wrong with the Fuji X-Pro 1 test on Dpreview

    Move the little square over the image (the Queen's face near the
    centre) and look at it. Use whatever ISO you like raw or jpeg. What
    is with the big yellow diagonal streaks going across the face? It's
    either near absent or absent in other camera images. I know the Fuji
    doesn't have an AA filter and it has an unusual sensor, so could it be
    some kind of moire?

    I don't see what yellow streaks you are referring too in the Fuji image.
    I zoomed in on the upper face of the queen of hearts, Nothing.
    Then I checked the lower face, again nothing.

    Yup! that was the page I checked. The only yellow I see is the yellow
    in the card design, no streaks in either of the Queen faces.
    I even checked my display calibration, and still have no yellow streak.

    I think he means the statue like image of the queen, not the card. And
    yes, it looks like some kind of moire effect to me.
    But perhaps not due the weird sensor, as exactly the same kind of
    yellowish banding can be seen on the roman (?) chap to the left of the
    queen in the Sony NEX 7 Image.

    Rich must spend an awful lot of time going through these samples on
    DPReview to find this stuff.

    No, I mean the Canadian money image. I'll check it on another
    computer to be sure. It didn't take long to see. In that scene, I
    usually look at the money and the clock.

    I cropped the image out. This is a piece of the JPEG image, the RAW
    shows it too, at 200-1600 ISO anyway.

    Now, the yellow bands run diagonally from left top to right bottom,
    across the hair and face. They appear (depending on your monitor
    size) about 1cm wide.

    That's what I was referring to - look at the NEX 7 image of the guy at
    the other end of the note. Same yellow bands.
    He looked roman to me - who the hell is that guy? Has there ever been a
    famous Canadian?
    You Canadians also need to update the picture of the queen, she's much
    more shrunken and wrinkly these days, the dear old soul.

    When you said Queen, the only Queen I could readily ID was the Queen of Hearts.

    Looking at the image on the bank note I see the image of a woman, but I
    can't ID her as any Queen of England I am familiar with. Are you sure
    that is a Canadian bank note? It certainly isn't Vicky or Liz-2 at any
    age. The choker type medallion is not the sort of thing the current
    resident of the throne would typically decorate herself with. I would
    suggest some other Victorian/Edwardian era female. I first thought
    perhaps Marie Curie, but she is not a match.

    That said there is certainly a yellow tint in what I believe is an
    anti-counterfeiting feature of that particular note. I can see it in
    all the images. I don't believe the yellow is going to disappear in any
    test image.

    Damn! I am a researching fool!

    The bank note is not Canadian, and the image is not a Queen, but an
    educator. It is a 1000 Lira bank of Italy note honoring Maria
    Montessori.

    The yellow appears in most photographs of the note and I believe that
    it is an anti-counterfeit measure.

    Thank you.
    That's not him on the Banknote - is it?

    I agree the yellow banding is clearly visible on the Queen's image
    from a banknote.

    However, if you read the text on the same page, the reviewer suggests
    that processing the image in Adobe Camera Raw may be sub-optimal:

    "Using our standard processing, with Adobe Camera Raw's noise
    reduction set to a minimum, the X-Pro1's images look distinctly
    different to those from Bayer sensor cameras, and specifically show
    much lower chroma noise. This means that direct comparisons have to be
    treated with caution; in effect the demosaicing required by the
    X-Trans CMOS sensor includes a degree of chroma NR. ACR also shows
    processing artefacts in various areas of the image, and can't match
    the camera's JPEGs in rendering some of the very finest detail, for
    example on the banknotes."

    Kind of odd that it manifests as a geometric pattern instead of random
    "noise" but I guess anything is possible?

    For that, I'd have to be working for Dpreview. :)

    Anyway, I tried a number of other cameras on that comparison tool,
    didn't see the same effect. I guess the users of Fuji are going to
    have to experiment a lot with other raw processors.

    I did some Google snooping before I read this (using Gio Pino as a
    search term) and found the 1,000 note too. Maria was the first woman
    in Italy to qualify as a physician. The back of the note honors
    teachers with a more modern image.

    http://www.banknotebank.com/note/932592

    Maria seems to have contracted jaundice.

    I would have said that saying Maria was an educator was wrong, but
    Floyd would consider that a "profession flame", and we don't want to
    stir Floyd up, do we?
