For our camera calibration, we used our Hewlett-Packard digital camera and a spectroradiometer. When gathering data, each was affixed to a camera mount with a steady light source.
            We first took readings of the Macbeth ColorChecker with the spectroradiometer, and converted the output to XYZ values. We next took an image using the camera of the entire Macbeth ColorChecker

    Using software provided to us by Michael Bax, we isolated the nonlinear RGB values of each swatch on the chart.
