Camera devices are calibrated by taking a photograph of a target under the desired lighting conditions. By converting the RAW file to a TIFF file, it can be used to calibrate the camera device in the color control panel.
You will need to crop the TIFF file so that just the target is visible. Ensure the white or black borders are still visible. Calibration will not work if the image is upside-down or is distorted by a large amount.
The resulting profile is only valid under the lighting condition that you acquired the original image from. This means you might need to profile several times for studio, bright sunlight and cloudy lighting conditions.
