    Converting Kelvin to asShotNeutral matrix

    login94

      Hello I'm trying to understand how convert Kelvin temperature to correct asShotNeutral matrix.

      Basically my camera produce pure RAW file without additional Info. I can convert proprietary RAW encoding to DNG but I don't know how automatically calculate asShotNeutralMatrix (the only dynamic matrix in DNG).

      The only info I know is the correct white balance expressed in kelvin during the shot.

      I know also color, forward and camera calibration matrices.

      I've read official Adobe documentation but I can't understand how reach this result. If someone could explain me why asShotNeutral has always this form {xxxx, 1, xxxx} and how calculate the 'x' with info I know (Hoping to have all what I need).

      Thank you!
