AWhite Balance Fine-Tuning

If white balance has been fine-tuned, an asterisk (“E”) will be displayed next to the white balance setting. Note that the colors on the fine- tuning axes are relative, not absolute. For example, moving the cursor to B (blue) when a “warm” setting such as J(incandescent) is selected for white balance will make photographs slightly “colder” but will not actually make them blue.

A“Mired”

Any given change in color temperature produces a greater difference in color at low color temperatures than it would at higher color temperatures. For example, a change of 1000 K produces a much greater change in color at 3000 K than at 6000 K. Mired, calculated by multiplying the inverse of the color temperature by 10 6, is a measure of color temperature that takes such variation into account, and as such is the unit used in color-temperature compensation filters. E.g.:

4000 K–3000 K (a difference of 1000 K)=83 mired7000 K–6000 K (a difference of 1000 K)=24 mired

When WB bracketing is selected for Custom Setting e6 (Auto bracketing set, 0 284), the camera will create several images each time the shutter is released. White balance will be varied with each image, “bracketing” the value currently selected for white balance (0 202).
