47 Adjusting the white balance and black balance Adjusting the white balance 1Set the switches as shown in the figure. FILTER controlWHITE BAL: A or B OUTPUT: CAM GAIN: Normally 0 dB Set to a more suitable gain level if it is too dark. When the GAIN and WHITE BAL switch settings are changed, messages advising the user of the set positions appear on the setting change message display of the viewfinder screen. (However, this happens only when “3” has been set as the display mode.) 2Select the FILTER control setting in accordance with the lighting conditions. OFor examples of the FILTER control settings, refer to the description of the FILTER control (page 13) in the “Shooting (recording)/playback function section.” When the FILTER control setting is changed, a message advising the user of the set positions appears on the setting change message display of the viewfinder screen. (However, this happens only when “3” has been set as the display mode.) A better picture can be achieved by adjusting the white balance and black balance in the following sequence: AWB (white balance adjustment) 5ABB (black balance adjustment) 5AWB. There is usually no need to re-adjust the black balance even when the power has been turned off and back on. The white balance must always be re-adjusted when the lighting conditions have changed. If the display mode is set to “2” or “3,” messages advising the user of what progress has been made in the adjustments and what the adjustment results are appear on the viewfinder screen when the black balance or white balance adjustment is commenced. Set the display mode to “1” if these messages are not to be displayed. OFor details on the display mode settings, refer to “Display modes and setting change messages” (page 43). OABB must be performed when the MASTER GAIN levels have been changed on the LOW SETTING, MID SETTING and HIGH SETTING screens of the CAM MENU, when the super gain setting has been changed using the USER button, and when the GAMMA (ON/OFF) has been switched on the CAMERA SETTING screen. OWith artificial lighting—particularly fluorescent lights and mercury lamps—the luminance may appear to be constant but the intensity of the R, G and B colors will change in synchronization with the power line frequency. Especially in regions with a 50 Hz power line frequency, mutual interference arises between the vertical sync frequency (approx. 60 Hz) of this unit and lighting frequency (50 Hz). As a result, the hue tends to change with the passage of time or flickering occurs, making it impossible to achieve a proper white balance. It is recommended that the white balance be achieved using the settings shown in the table below. Power line frequencyShutter speed 50 Hz1/100 60 HzOFF
48 Adjusting the white balance and black balance Adjusting the white balance 3Erect 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. 4Adjust the lens aperture. 5Set 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. At least one-fourth of the screen width At least one-fourth of the screen height Take care to keep high-brightness spots off the screen. 6While 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 AUTO W/B BAL switchMessage appearing while the adjustment is in progress 7Adjustment 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 Message appearing upon completion of the adjustment 8A message such as the following appears if the color temperature of the subject is lower than 2500 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. 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 inconsistant. AWB A OK 2.5K m When the color temperature is lower than 2500 K AWB A OK 5.6K m When the color temperature is higher than 5600 K
49 Adjusting the white balance and black balance Adjusting the white balance When the white balance cannot automatically be adjusted An error message appears on the viewfinder screen (when “2” or “3” has been set as the display mode). When there is no time to adjust the white balance Set the WHITE BAL switch to PRST. The white balance for the filter is achieved in accordance with the setting position of the FILTER control (outer). White balance memories There are two sets of white balance memories, A and B. When the FILTER INH setting on the CAMERA SW MODE screen of CAM MENU is ON (default setting), the number of memories for set A and set B is limited to one each. In this case, the memory contents are not coupled with the filter. When FILTER INH is set to OFF, the adjustment values for each filter can be automatically saved in the memories corresponding to the WHITE BAL switch settings (A or B). This unit contains four filters so that a total of 8 (4a 2) adjustment values are saved. When any of the error messages listed above is displayed, take the recommended action, and try adjusting the white balance again. If the error message persists even after repeated attempts, consult your dealer. On rare occasions, AWB cannot be adjusted and a NG display appears. In a case like this, adjust AWB again. Messages relating to white balance adjustment Error messageMeaning Recommended action Select a suitable filter. COLOR TEMP. HIGHColor temperature is too high. Select a suitable filter. COLOR TEMP. LOWColor temperature is too low. Increase the amount of light or increase the gain. LOW LIGHTThere is not enough light. Reduce the amount of light or reduce the gain. LEVEL OVERThere is too much light. If flickering is to blame, install the shutter, and stabilize the shooting conditions. UNSTABLE CONDITIONThe shooting conditions are unstable (shooting under fluorescent light, unstable camera posture, etc.).
50 Adjusting the white balance and black balance Adjusting the white balance When FILTER INH is set to ON When AWB is adjusted, the color temperature and filter number applying at the time are displayed. If the filter is then turned, the color temperature and filter number are displayed. The white balance is almost fully adjusted if the subject is illuminated at a color temperature approaching the one displayed. AWB is adjusted using subject filter (B) with a lighting color temperature of 3200 K. (Example of display) AWB A OK 3.2K 7 The filter is changed to filter (C) 7 The filter (B) is restored. 7 “4.3 K (B)” is displayed. (1): This indicates that AWB was adjusted using the filter. 4.3K(B) 7 “3.2 K (B)” is displayed, and the status when AWB was first adjusted is indicated. 3.2K(B) If the color temperature of the subject in this state is near 4.3 K, the white balance is right and so the camera can be used. 7
