  • 2. White Balancing
  • 3. White Balance
    • We see the world in many different tints of light
    • The problem is that our brains adjust what we see to filter out these tints, so we are often unaware that they exist at all...
  • 4. White Balance
    • Consider a summer’s day:
    • We might have a red dawn glow to begin with…
    • By noon, when the sun is high, we have bright yellow…
    • It might rain later, softening the light through grey clouds…
    • Before returning to a red sunset...
  • 5. White Balance
  • 6. White Balance
    • Things get more complex when we add artificial lighting (light bulbs, etc...) into the mix:
  • 7. White Balance
  • 8. White Balance
    • The reason that pictures have an orange tint with light bulbs and blue with fluorescent lights is because different lights have different colour temperatures
    • This is a huge topic – for now just accept that different lighting gives off different tints
  • 9. Our Brains are Smart...
    • And all the time our brain is ‘adjusting’ our perception of these changing tints:
  • 10. ...Camcorders are Dumb
    • Unfortunately a camcorder is not as clever as our brains
    • It has no idea what colour light it is filming in (despite advances in automatic sensors). This usually produces some pretty horrendous tints
  • 11. Setting the White Balance
    • Therefore you need to tell your camcorder what tint of light it is filming in
    • This is known as White Balancing
  • 12. The Science Bit
    • White Balance works on the fact that all colours can be produced from pure white light (think of Newton and his prisms):
    Pure White Light... ...can be split into a rainbow of colours (With apologies to Pink Floyd!)
  • 13. What all this Means
    • So if we tell a camcorder what white looks like in a given light, it can work out what every other colour should look like. This produces accurate colours, especially natural skin tones:
  • 14. It’s not Difficult
    • The Golden Rule:
    • White Balancing is dead easy to do and must be done at every new location
  • 15. White Balancing a Camera
    • Simply find the Manual White Balance control on your camcorder (but don’t press it yet). Then get somebody to hold up a sheet of white paper:
    Camcorder White Card
  • 16. White Balancing a Camera
    • Zoom in so that the white paper completely fills the screen:
    • ...then press the Manual White Balance button -
  • 17. ‘ I can’t find the WB button!’
    • The biggest problem you will face is finding the White Balance control
    • Every camcorder has a different way of setting the White Balance – some have buttons, some use an on-screen menu, and some set the WB at the moment they are switched on! Good Luck!
