Similar to White Balance Auto Bracketing, you can also manually set the color bias of images to a single bias setting by using White Balance Correction. The color can be biased toward blue (B), amber (A), magenta (M), or green (G) in +/- nine levels measured as mireds, or densities. Each level of color correction that you set is equivalent to five mireds of a color-temperature conversion filter. When you set a color correction or bias, it is used for all images until you change the setting. #
Note On the Rebel XSi/450D, color compensation is measured in mireds, a measure of the density of a color-temperature conversion filter that range from 0.025 to 0.5. Shifting one level of blue/amber correction is equivalent to five mireds of a color-temperature conversion filter.
3.12 This image was taken in tungsten light with a White Balance Correction of Blue 3/Magenta 1 to neutralize the yellow color but retain a bit of the warmth of the light. Exposure: ISO 100, f/2.8, 1/50 second with +0.33 Exposure Compensation.
The White Balance Correction technique is much like using a color-correction filter for specific light sources.
To set White Balance Correction, follow these steps:
