AWhite Balance Fine-Tuning
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.
AColor Temperature Fine-Tuning
When  Choose color temp.  is selected, you can view the 
color temperature while fine-tuning white balance.
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 106, 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 mired
• 7000 K–6000 K (a difference of 1000 K)=24 mired

Preset Manual
Preset manual is used to record and recall custom white balance settings for shooting 
under mixed lighting or to compensate for light sources with a strong color cast.
 The 
camera can store up to six values for preset white balance in presets d-1 through d-6.
 
Two methods are available for setting preset white balance:
❚❚ Measuring a Value for  White Balance During Viewfinder Photography
