Session 7 White Balance (Basic Photography Class)

  1. 1. White Balance and Color Temperature MC 310: Basic Photography Bong S. Eliab Mass Communication Program
  2. 2. Outline §  White Balance Explained §  Color Temperature §  How to compensate color temperature §  How to get the actual colors §  Color cast as effects
  3. 3. White Balance §  Is a way to correct the colors in the photograph taking into account the light it was shot with; §  Why correct the colors? - not all light sources produce the same light quality and temperature equally across the whole visible light spectrum

  12. 12. Color Distribution
  13. 13. Raw Format §  Use the RAW file format (if your camera supports them). §  Allows you to set the WB after the photo has been taken. §  Allows you to set the WB based on a broader range of color temperature and green-magenta shifts.
  14. 14. Raw Format Advantage
  15. 15. Mixed Lighting: Problem §  AWB usually calculates an average color temperature for the entire scene, §  AWB Uses average temperature as the white balance §  AWP - Acceptable approach §  However AWB tends to exaggerate the difference in color temperature for each light source
  16. 16. Mixed Lighting Note: • Building to the left is quite warm • But the sky is somewhat cool •  WB was set based on the moonlight-bringing out the warm color temperature of the artificial lighting below •  White balancing based on the natural light often yields a more realistic photograph.
  17. 17. Automatic White Balance
  18. 18. AWB §  white balance is available in all digital cameras and uses a best guess algorithm within a limited range-- usually between 3000/4000 K and 7000 K.
  19. 19. Custom White Balance
  20. 20. Neutral Reference
  21. 21. Automatic and Manual WB Automatic White Balance Custom White Balance Custom WB uses 18% gray reference point.
  22. 22. Custom White Balance §  Custom white balance allows you to take a picture of a known gray reference under the same lighting, and then set that as the white balance for future photos.
