An introduction to White Balance, the underused control

PC Review: "The human eye has a remarkable ability to adjust to different light conditions. Not only do our eyes have built-in auto-focus system and auto-exposure capability, but we also have automatic colour balance built into our brains. A white object will appear white to us whether viewed in sunlight or under overcast skies, or indoors under incandescent or fluorescent lighting that is because the human brain has the capability to compensate for such changes in perceived colour. A very efficient system indeed!"
