Chapter 4 Adjustments and settings for recording

In order to achieve images with a consistently high picture quality with this unit, it is necessary to adjust the black balance and white balance as the individual conditions demand. To achieve a higher picture quality, it is recommended that the adjustments be performed in the following sequence: AWB (white balance adjustment) > ABB (black balance adjustment) > AWB (white balance adjustment).

4-1 Adjusting the white balance and black balance

4-1-1 Adjusting the white balance

The white balance must always be re-adjusted when the lighting conditions have changed.

The white balance is adjusted automatically by following the steps below.

1 Set the switches as shown in the figure.

CC FILTER/ND FILTER controls

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.

<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 4 will stop.

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

6 While the adjustment is in progress, the following message appears on the viewfinder screen.

AWB ACTIVE

 

WHITE BAL: A or B

 

OUTPUT: CAM

AUTO W/B BAL switch:

GAIN: Normally 0 dB

Use this to execute AWB.

Set to a more suitable gain level

 

if it is too dark.

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

8 The message shown in the figure below appears when the color temperature of the subject falls below 2300 K or rises above 5600 K.

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

2 Select the CC FILTER/ND FILTER controls setting in accordance with the lighting conditions.

<Note>

For examples of the FILTER controls settings, refer to “2- 3 Shooting and recording/playback function section.”

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.

<Notes>

Take care to keep high-brightness spots off the screen.

Shoot white objects in the center of the screen.

At least one-fourth of the screen width

AWB A OK 2.3K m
