White Balance
About White Balance
White balance ensures that colors appear natural regardless of the color of the light source. The default setting (4) is suitable for use with most light sources, but if it fails to produce the desired results, other settings can be selected according to the weather or light source.
Adjusting White Balance
White balance can be adjusted using the [White balance] items in the i menu, photo shooting menu, or video recording menu.
At default settings, white balance can also be selected by holding Fn1 button and rotating the main command dial. The selected option is shown by an icon in the shooting display.
Options for the selected setting, if any, can be chosen by holding the Fn1 button and rotating the sub-command dial.
| Option | Color temperature * | Description | |
|---|---|---|---|
| 4 [Auto] | The camera adjusts white balance for optimal results with most light sources. If an optional flash unit is used, white balance will be adjusted in accord with the conditions in effect when the flash fires. | ||
| i [Keep white (reduce warm colors)] | Approx. 3500–8000 K | Eliminate the warm color cast produced by incandescent lighting. | |
| j [Keep overall atmosphere] | Approx. 3500–8000 K | Partially preserve the warm color cast produced by incandescent lighting. | |
| k [Keep warm lighting colors] | Approx. 3500–8000 K | Preserve the warm color cast produced by incandescent lighting. | |
| D [Natural light auto] | Approx. 4500–8000 K | White balance is adjusted for non-artificial light sources, producing more life-like colors than does [Auto] when used under natural light. | |

Values when fine-tuning is set to 0.
D [Natural light auto] may not produce the desired results under artificial light. Choose 4 [Auto] or an option that matches the light source.
4 [Auto] may not produce the desired results with large studio flash units. Use preset manual white balance or set white balance to 5 [Flash] and use fine-tuning to adjust white balance.
- The photo info [Basic shooting data] page for pictures shot with 4 [Auto], D [Natural light auto], or L [Preset manual] selected for white balance lists the color temperature in effect at the time the picture was taken (0 Basic Shooting Data). You can use this as reference when choosing a value for K [Choose color temperature].
- To view the [Basic shooting data] page during playback, go to [Playback display options] in the playback menu and place checks (M) next to [Shooting data] and [Basic shooting data].
- Color temperature is not shown for pictures taken using high-speed frame capture +.
White balance can also be adjusted from the photo shooting and video recording menus.
The perceived color of a light source varies with the viewer; some may have a red cast while others appear blue. Color temperature is an objective measure of the color of a light source, expressed in Kelvins (K). The lower the color temperature, the redder the cast (q); the higher the temperature, the bluer the cast (w).
In general, choose lower values if your pictures have a red cast or to intentionally make pictures bluer, higher values if your pictures are tinged blue or to intentionally make pictures redder.
Fine-Tuning White Balance
Each white balance option can be fine-tuned by up to six steps in either direction from the center along both the A (amber)–B (blue) and G (green)–M (magenta) axes.
Using Buttons
Choose a white balance option by holding the Fn1 button and rotating a command dial.
Keeping the Fn1 button pressed, fine-tune white balance using the multi selector.
- Use the multi selector to position the cursor on the grid. The selected value is displayed to the right of the grid.
- The A (amber)–B (blue) axis corresponds to color temperature and is ruled in increments of 0.5. A change of 1 is equivalent to approximately 5 mired.
- The G (green)–M (magenta) axis has effects similar to color compensation filters and is ruled in increments of 0.25. A change of 1 is equivalent to approximately 0.05 diffuse density units.
Save changes.
- The selected setting takes effect when the Fn1 button is released.
If white balance has been fine-tuned, an asterisk (“U”) will appear in the white balance icon.
Using the Menus
Select [White balance] in the photo shooting or video recording menu, highlight the desired option, and press 2 as often as necessary to display fine-tuning options.
For information on fine-tuning [Preset manual] white balance, see “Fine-Tuning Preset Manual White Balance” (0 Fine-Tuning Preset Manual White Balance).

To choose a white balance setting using the command dials, press the Fn1 button while shooting information is displayed. The selected setting can be fine-tuned using the multi selector while the Fn1 button is pressed.
The colors on the fine-tuning axes are relative, not absolute. Selecting more of a color on a given axis does not necessarily result in that color appearing in pictures. For example, moving the cursor to “B” (blue) when a “warm” setting such as J [Incandescent] is selected will make pictures slightly “colder” but will not actually make them blue.
Values in mired are calculated by multiplying the inverse of the color temperature by 106. 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 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.: Change in color temperature (in Kelvin) : Value in mired
- 4000 K – 3000 K = 1000 K : 83 mired
- 7000 K – 6000 K = 1000 K : 24 mired

Preset Manual
White balance settings such as 4 [Auto], J [Incandescent], and K [Choose color temperature] may fail to produce the desired results under mixed lighting or lighting with a strong color cast. Should this occur, white balance can be set to a value measured under the light source used in the final photograph. Two methods are available for setting preset white balance:
| Method | Description |
|---|---|
| Direct measurement | Measure white balance in a selected area of the frame (0 Direct Measurement). |
| Copying a value from existing photograph | Copy white balance from a photo on a memory card (0 Copying White Balance from a Photograph). |
Direct Measurement
The camera can store up to six values for preset manual white balance.
Hold the Fn1 button and rotate the main command dial to select L.
Select a preset.
Hold the Fn1 button and rotate the sub-command dial until the desired white balance preset (d-1 to d-6) is displayed.
Select direct measurement mode.
- Release the Fn1 button briefly and then press it again to enter direct measurement mode. L will flash in the shooting display.
- A white balance target (r) will appear in the center of the frame.
Position the white balance target (r) over a white or gray object and measure a value for preset manual white balance.
- Position the target (r) using the multi selector.
- To measure white balance, press the shutter-release button all the way down or press J. White balance can be measured multiple times while direct measurement mode is in effect.
- You can also position the target (r) and measure white balance by tapping the display.
- Target selection will not be available if an optional flash unit is attached. Frame the shot so that the white or gray reference object is in the center of the display.
- If the camera is unable to measure white balance, a message will be displayed and the camera will return to direct measurement mode. Try measuring white balance again, for example with the target (r) positioned over a different area of the subject.
Press the i button to exit direct measurement mode.
