6. SETTING AND ADJUSTMENTS BEFORE SHOOTING 6-5 White Balance Adjustment Since the color of light (color 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 color temperature of 3,200K is shot while the color temperature conversion filter setting is set to 5,600K, a proper white balance adjustment and (FAW) Full Time Auto White balance may not be accomplishable. In this case, change the color 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. WHITE BALANCE ADJUSTMENT 2. FILTER knob 1. IRIS mode switch Two kinds of white balance adjustment results can be stored in memories AUTO1 and AUTO2. Adjustment procedure 1. Set the following switches. • Set the POWER switch to ON. • Set the OUTPUT switch to CAM-AUTO KNEE OFF. • Set the IRIS mode switch of the lens to A (Auto). 3. WHT.BAL switch 2. Set the FILTER knob according to the current lighting. 3. Set the WHT.BAL switch to A or B. 5. AUTO WHT. /ACCU FOCUS switch 1. OUTPUT switch 1. POWER switch A U T O WH I T E A OPERA T I ON During operation A U T O WH I T E A OK Result message 4. Place a white object near the centre of the screen under the same lighting conditions as the target subject and zoom in to fill the screen with white. 5.Tilt the AUTO WHT./ACCU FOCUS switch upward (to AUTO WHITE) once and release it. "AUTO WHITE A, B OPERATION" is displayed in the viewfinder while the auto white balance adjustment circuit operates. "AUTO WHITE A, B OK" is displayed when the white balance has been adjusted properly. Error messages A U T O WH I T E A NG : OB J ECT Improper object A U T O WH I T E A ERROR : OVER L I GHT A U T O WH I T E A E RROR : L OW L I GH T Insufficient illumination • NG: OBJECT (Improper object) Displayed when there is not enough white color on an object or the color temperature is not suitable. Replace the color 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)
Excessive illumination Displayed when the light is excessively bright. Decrease the illumination and then re-adjust the white balance. 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 item "FAW" on the OPERATION MENU. This item allows allocation of the FAW function to one of the WHT.BAL switch positions, A, B or PRESET. See "OPERATION Screen" on page 73. 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 color or not enough white color. • 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. 45 6.

To record the GY-DV500's signal, set to "CAMERA". See page 68. ● LOW CUT IN For each audio input connector, select whether or not the lower frequency components of the audio signal are cut. Set to this position to eliminate the wind noise of the microphone. ● SAMPLING RATE Select the sampling rate for audio recording (48 kHz or 32 kHz). ● FRONT VOLUME ENABLE Set whether or not the front section's audio volume control should be used. The front section's audio volume control only affects the CH1 audio channel. ● LONG PAUSE TIME Select the time (in minutes) until the GY-DV500 enters the tape protection mode (drum rotation stops) when the recordpause mode is continued for long time. ● SSF MODE Select the mode of the S.S.F. (Super Scene Finder) function. S.S.F. function: Stores the time code of desired scenes or cue points in the unit's memory. See "How to Use the S.S.F.

Setting the time code recording function The GY-DV500 records SMPTE-standard time code for U-ver. or EBU-standard time code for E-ver. during recording. Set the switches according to applications. ● To record a time code as set in the built-in time code generator: • Set the PRESET/REGEN switch to PRESET. • Set the REC/FREE switch. If it is required to record continual time codes across different scenes, set the switch to REC. • VCR Setup Menu setting (U-ver. only) Select the time code generator's framing mode as drop frame or non-drop using the VCR Setup Menu item No. 416 "NON DROP/DROP". ● To record a time code in continuation of the existing time code on the tape: • Set the PRESET/REGEN switch to REGEN.
