binsurf - well, i think about adding an option to change the extension to dng automatically, if dng is activated.

ewavr: the dng defines for the g7 seem to be off, i have a report in the german forum about the dngs being too small, they seem to be cropped.
looking at the defines:

    #define CAM_RAW_ROWPIX              3736   // for 10 MP
    #define CAM_RAW_ROWS                2772   // for 10 MP
versus
    #define CAM_JPEG_WIDTH  3072
    #define CAM_JPEG_HEIGHT 2304
theres a whole lot of pixels missing, and not the usual small amount.
isnt the following more likely:
    #define CAM_JPEG_WIDTH  3648
    #define CAM_JPEG_HEIGHT 2736

???
i dont know how to calculate the rest, so somebody else gotta fill it in (ewavr?).

OMG, for G7 all DNG settings was incorrect  :'(
Correct settings can be copied from DGN4PS2 settings:

    // pattern
    #define cam_CFAPattern 0x02010100 // Red  Green  Green  Blue
    // color
    #define CAM_COLORMATRIX1                              \
      575419, 1000000,-185557, 1000000, -77898,  1000000, \
     -213702, 1000000, 733569, 1000000,   81514, 1000000, \
      -24604, 1000000, 131906, 1000000,  280378, 1000000
   
    #define cam_CalibrationIlluminant1 1 // Daylight
    // cropping
    #define CAM_JPEG_WIDTH  3648
    #define CAM_JPEG_HEIGHT 2736
    #define CAM_ACTIVE_AREA_X1 14
    #define CAM_ACTIVE_AREA_Y1 8
    #define CAM_ACTIVE_AREA_X2 3682
    #define CAM_ACTIVE_AREA_Y2 2764

btw there is a function in my s3is dump - GetDefectCount. i dont know what it does, but from the sound of it i would assume it returns the number of badpixels maybe?
oh and btw since we have dng now, we soon dont need jpgs anymore. so i thought it would be a nice feature to have an extra checkbox like "set jpgs smallest size if dng is activated", which would automatically set the propcases for size = small and compression = high.
but i have the same problem as in s-series - enable flash during video recording for still images (in trunk now!), i dont know where and how to restore the size & compression settings.

On A710 it returns zero value. Maybe it works only in adjustment mode,

In #623:
- added 'DNG' extension for DNG files (you must use card reader to access them),
- added empty ImageDescription tag, proposed by MartinBudden,
- fixed color matrix for a590
- added possibility to create badpixel.bin from script (attached here). Before script is started, user must set shutter speed to 1/4 - 1s and make several shoots to ensure that badpixel count is the same (how make this in script?)

Nice!

Is it necessery to hold something in front of the lens, so the camera takes a "darkframe", in order to create the badpixel file?

Add this to the line above the shoot command;

if get_propset() == 2 then
   set_prop(264,0)
else
   set_prop(69,0)
end

That will automatically set the shutter to 1".
