Adjusting the white balance and black balance (continued)

Adjusting the white balance

3 Erect a white pattern at a place with the same conditions as the source of light illuminating the subject, zoom in, and shoot the white of the pattern on the screen.

A white object (such as a white cloth or white wall) near the subject may be used as a substitute for the white pattern.

The size of the white object required is shown in the figure below.

At least one-fourth of the screen width

At least one-fourth of the screen height

6 While the adjustment is in progress, the following message appears on the viewfinder screen (but only when “2” or “3” has been set as the display mode).

AWB ACTIVE

7 Adjustment is completed in several seconds. (A message similar to the one shown in the figure now appears.)

The adjustment value is automatically saved in the memory (A or B) which was set in step 1.

AWB A OK 3.2K

<Notes>

OTake care to keep high-brightness spots off the screen. OShoot white objects in the center of the screen.

4 Adjust the lens aperture.

5 Set the AUTO W/B BAL switch to AWB, and then release it.

The switch returns to the center, and the white balance is automatically adjusted.

AUTO W/B BAL switch

<Note>

When the AUTO W/B BAL switch is pressed again to the AWB side when the white balance is being adjusted automatically (AWB ACTIVE), the adjustment operation will stop.

The adjusted value in this case is the value before automatic adjustment was performed.

Message appearing upon completion of the adjustment

8 A message such as the following appears if the color temperature of the subject is lower than 2300 K or higher than 5600 K.

The downward pointing arrow indicates that the color temperature is lower than the display temperature; conversely, the upward pointing arrow indicates that the it is higher than the display temperature.

AWB A OK 2.3K m

When the color temperature is lower than 2300 K

AWB A OK 5.6K m

When the color temperature is higher than 5600 K

<Note>

When a zoom lens with an automatic aperture function is used, aperture hunting may occur. Adjust the aperture’s gain control (marked as IG, IS, S, etc.) provided with the lens.

For details, refer to the operating instructions which accompany the lens.

Hunting:

The auto iris response is repeated, causing the brightness levels of the image to become inconsistent.
