Photography: 5 - White Balancing

  1. 1.  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...
  2. 2. 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...
  3. 3. Things get more complex when we add artificial lighting (light bulbs, etc...) into the mix:
  4. 4.  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
  5. 5.  And all the time our brain is ‘adjusting’ our perception of these changing tints:
  6. 6.  Unfortunately a camera 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
  7. 7.  Therefore you need to tell your camera what tint of light it is filming in  This is known as White Balancing
  8. 8.  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!)
  9. 9.  So if we tell a camera 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:
  10. 10. The Golden Rule:  White Balancing is dead easy to do and must be done at every new location  At the very least use Auto or one of the preset modes
  11. 11.  Simply find the Manual White Balance control on your camera (but don’t press it yet). Then get somebody to hold up a sheet of white paper: Camera White Card
  12. 12.  Zoom in so that the white paper completely fills the screen:  ...then press the Manual White Balance button or whatever option your camera has
  13. 13.  The biggest problem you will face is finding the White Balance control  Every camera 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!
