For comparison purposes, here is the picture I posted:
And here an unprocessed jpeg from one of the RAW (digital negative) files the above photo was made from. This jpeg was taken one stop underexposed from what the camera read as correct exposure.
You can see how the tone enhancements have altered the tobac color a bit. I used a WB setting of around 5000 or 5500k, so it is slightly warmer than what the camera AWB selected, somewhere around 4000k.
