How to apply white balance coefficents to RAW image for sRGB output The solution is based on Processing RAW Images in MATLAB guide I am posting both MATLAB implementation and Python implementation (but no Rust implementation) The first step is extracting the raw Bayer image from sample dng using dcraw command line: dcraw -4 -D -T sample dng Rename the tiff output to sample__lin_bayer tif
[rec_raw] Whitebalance AsShotNeutral in Raw-Header? The question is how to get actual values of "WB RGGB Levels As Shot" and "Color Temp As Shot" directly from the body an convert them to DNG AsShotNeutral format
Questions about black-level and white-levels in colordata white is either format maximum (defined by bits per pixel), or maximum value defined by metadata (DNG whitelevel) linear_max is 'specular white' read from metadata (if present in file)

Decoding White Balance - RAW Shooting and Processing - CHDK Forum The modify WB setting isn't even documented for my camera, but there's some good info in the DNG standard that explains WB in general The camera allows 19 settings on two axis for modify a base WB
Comparing two images to see if theyre identical - GitHub Do the same for your DNG file and look at the differences between the two results from identify -verbose You will see the two are different I also note that your DNG seems to be doing some white balance (wb) (and red balance, rb) as I see
Canon 350D WB RGGB Levels - exiftool. org What puzzles me is the interpretation of the WB RGGB Levels The image was taken with the camera set to WB = Daylight, and this is shown correctly next to the tag White Balance
