In this filmmaking class, Karl explains colour temperature and shows you how to adjust your camera settings to achieve the right colour temperature in your videos.  Beginning by explaining colour temperature and the Kelvin scale on which it is measured, Karl illustrates the difference between cold (blue), neutral (white) and warm (orange) light.  He then shows you how to adjust the White (or Colour) Balance setting on your camera to suit (and, if necessary, neutralise) the colour temperature of the light on set.
