JVC GY-DV5001 manual White Balance Adjustment

6. SETTING AND ADJUSTMENTS BEFORE SHOOTING

6-6 White Balance Adjustment

Since the colour of light (colour temperature) varies depending on the light source, it is necessary to re-adjust the white balance when the main light source illuminating the subject changes.

Note

When a subject illuminated by a halogen lamp with a colour temperature of 3,200K is shot while the colour temperature conversion filter setting is set to 5,600K, 5,600K+1/8 ND, or 5,600K+1/64 ND, a proper white balance adjustment and (FAW) Full Time Auto White balance may not be accomplishable. In this case, change the colour temperature conversion filter setting to 3,200K and then carry out the white balance adjustment and (FAW) again.

●Do not adjust using any highly reflective objects, such as metal, etc., as this may result in improper white balance adjustment.

FULL-TIME AUTO WHITE BALANCE (FAW)

The FAW function adjusts the white balance value automatically as the lighting condition changes.

This mode is convenient when you have no time to adjust the white balance or when the camera is moved frequently in and out of places under different lighting conditions.

■Setting procedure

The FAW function can be activated with the FAW item on the CAMERA OPERATION menu screen. The FAW function can be allocated to one of the white balance switching switches A, B, or PRESET.

Error messages

If the adjustment ends abnormally, an error message, as described below, blinks for about 5 seconds.

●NG: OBJECT (Improper object)

Displayed when there is not enough white colour on an object or the colour temperature is not suitable.

Replace the colour temperature conversion filter or use another white object and re-adjust the white balance.

●ERROR: LOW LIGHT (Insufficient illumination)

Displayed when the illumination is dim. Increase the illumination and then re-adjust the white balance.

●ERROR: OVER LIGHT (Excessive illumination)

Displayed when the light is excessively bright. Decrease the illumination and then re-adjust the white balance.

CAUTION:

●The FAW (Full-time Auto White balance) function cannot provide optimum white balance with a subject outside the FAW adjustment range, for example when it contains only a single colour or not enough white colour.

●The accuracy of the FAW (Full-time Auto White balance) is inferior to that of the manual white balance.

●When the power is turned on with the FAW mode selected, it takes about 10 seconds for the FAW adjustment to be completed. Do not shoot within this interval.
