24ColorCard FAQ

How much improvement can I expect ?

This graphic shows the effect of different color balancing techniques. The combined effect of using both the GreyBalanceCard and the ColorCard clearly gives more accurate color.

Top row images:
  • Residual color cast using the camera's Auto White Balance (AWB)
  • Improved by using the CTrax GreyBalanceCard and camera Custom White Balance (CWB)
  • Little benefit from Photoshop CS4 Auto Adjust of the previous CWB image
Bottom row images:
  • Improvement via Picasa 3.8 correction based on CWB + 24ColorCard image
  • Better balance via CS4 Auto Adjust based on CWB + 24ColorCard image
  • Further refined via CS4 Selective Color based on CWB + 24ColorCard image
