The CBL Color Balance 110MM Lens is a valuable tool for proper color balance and consistency. This 2-sided disc comes complete with a gray side and a white side, allowing you to use one side for proper color balance and the other side for proper exposure. You simply hold the CBL in front of your camera and either make an evaluation or take a white-balance-reference picture.  You should assure that the subject's dominant light source is also falling upon the CBL.  Thanks to its complex, varied collection of prisms and lenses upon the 'white' side, the CBL grabs a large mixture of the light source and directs it into the camera during the white balance evaluation.
