Save RAW files in DNG format instead of RAW

PhyrePhoX

if a badpixel.bin was created in camera, it *should* also contain at least the platform id of the camera it was created in. and if loaded, should be matched against the platformid of the camera that is loading it. people who swap their sdcards between different cameras will get wrong results if there isnt a precaution coded like this (even people who swap cards between same models, but i guess we cannot detect that).

Keep up the good work.

The suffix .DNG seems not possible.
Is the prefix DNG_ would be possible?

Thank you

Yea, although serial number would be better, people are using SDM with multiple cameras of the same model after all.

oh, can we access the s/n number? i guess it is in the params somewhere. yes, serial number would be better than platform id.

Hmm.. I thought it was written in EXIF MakerNotes (and thus obviously accessible... those who've been working on DNG might know?) but on a quick check with exiftool I couldn't find it.

A serial number is visible via USB (e.g. in lshal output on Ubuntu), but it's true that this is something that could be written inside a USB subsystem and not easily accessible to us. But that's one way of getting the number so one can search for it in-camera.

Possible, but this changes behavior of the camera delete function. See Some notes on file prefix and extension treatment

Thank for the answer.

I have a big bug with the last firmware revision (613).
If i delete a picture, only the jpg is delete, the CRW is always in th SD.
Purge raw work but reboot camera doesn't work.

I take it we won't be seeing the .dng extension in our options for a while?

PhyrePhoX

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?).

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

shall i check it in?

Yes, please.

PhyrePhoX

done.

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?

binsurf

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".

No, bad pixels are detected by having a zero value, which is done automatically by the camera (presumably from it's own bad pixel list or other detection mechanism)
