    In fact, in the last five hours such a balloon took-off from Las Vegas, avoided Area 51 restricted airspace

    Hmmm  ... not quite  ... this has caused some problems.

    Waiting for return of payload.

    Hope 'they' enjoy examining my script !

    Well, they enjoyed it so much the personel at Nellis Air Force base deleted all movies and high-altitude images leaving just two hundred of Las vegas.

    Too bad I don't have any 'very little friends in very high places' !

    The satellites of foreign governments will have acquired far higher resolution images, what is their problem, or is it just procedure ?

    So, keep well away from Area 51 if you are thinking of launching a balloon in that area.

    Reconnaissance satellites fly in fixed, well defined orbits and it is relatively easy to determine when they will be overhead observing.  Obviously, things that the satellites are not supposed to see are done when they are not overhead.  A balloon hovering at altitude can have a very long "time over target" and a random arrival time.  So you can see why it might be policy to delete pictures taken by such a balloon as a matter of standard practice.

    ok.. so I was able to get DNG files from the CRW files using SDMdng ver 1.01 but the photos all come out with a magenta color..

    1. Download http://stereo.jpn.org/eng/sdm/file/common_files.zip

    2. Put RAW file in new directory "...\CANON\CRW".

    3. Run file "process.bat". It convert RAW to DNG.

    4. Install "RawTherapee_WinXP_32_4.0.4.2". If your PC not have RAM 2GB then run setup with this command: msiexec /a RawTherapeeV40x86Setup.msi TARGETDIR=c:\RawTherapeeV40x86

    5. Open DNG file in RawTherapee.

    6. Go to tab "Color" (Alt+C) and adjust "Color Channels" Red Green Blue.
    P.S. Russian is my native language.

    doesn't Photoshop have the ability to adjust color channels?

    I have tried to fix jakedoza's magenta image problem by using existing colour matrix values from other cameras with the same-size sensor.

    Namely, the A650,G9 and IXUS960 and the colour filter array order is Red Green Green Blue.
    It makes no difference.

    Highly unlikely the raw start address could be in error by exactly one line.

    Did someone recently mention an Adobe utility that allowed you to determine the matrix values ?

    My Photoshop doesn't support DNG files from this camera.

    You can try "Adobe DNG Profile Editor".

    1. SDM 1.85 doesn't make a "dark-frame subtraction".
    2. RAW is not saved when timer is used.
    3. SDM not support Lua scripts.
    4. IXUS 105 have 12MP, but RAW 10MP.
    5. PhotoME program says that DNG has 12 bits per component.
    6. If use "eLynx lab MSW" for demosaicing with method "Bin2X2" then output image resolution is 1842 x 1386  Pixels (2.55 MPixels).
    7. DNG has a distortion.
    8. The left and top areas of DNG, not exists in JPEG image.
    9. The right and bottom areas of JPEG, not exists in DNG image. Why they are not in RAW?

    Download "IXUS 105 RAW.zip" (RAW, JPEG, DNG) - 18.36MB from

    What do you think about IXUS 105 RAW image problems?

    This is curious.  AFAIK, this happens when the value of cam_CFAPattern in platform_camera.h is not set correctly.  I have been told that there are only two valid choices,  listed below.
    Code: [Select]
    #define cam_CFAPattern  0x01000201 // Green Blue Red Green
    #define cam_CFAPattern  0x02010100 // Red Green  Green  Blue
    Changing this value requires recompilation of the source code. 

    And as this is an SDM release rather than CHDK,  I'm not sure how much else we can do to help you here.
