BACK. L : Under back light (Opens the iris about 1 step from the standard level.) NORMAL: Normal condition SPOT. L : Under spotlight (Closes the iris about 1 step from the standard level.)  See "SWITCH FUNCTIONS" on page 83. 9 [GAIN] switch Electronically boosts the light sensitivity when there is insufficient illumination on the subject. The boosting level differs depending on the switch position as follows: (Factory presets) L : 0 dB (no boosting is applied) M : 9 dB (boosted to approximately 3 times the original) H : 18 dB (boosted to approximately 8 times the original) • The boosting level for each switch position can be changed with the OPERATION menu screen. ( See page 73.) The more the boosting level is increased, the more the resulting image will be noisy. 0 [VTR SAVE/STBY] switch Used to select the status of the GY-DV500 when the power is turned ON and a videocassette is loaded. STBY: The GY-DV500 is in the standby mode. When a recordable videocassette is loaded, the GY-DV500 enters the record-pause mode. SAVE: The GY-DV500 is in the save mode. • The status of the GY-DV500 is displayed on the Status screen 1 in the viewfinder. ! [OUTPUT] Color bar/Camera/Auto knee switch This switch is used to select the output signal. When the video signal from the shooting camera is selected, the auto knee function is available. CAM. AUTO KNEE ON: Outputs the video signal from the shooting camera. In this mode, the auto knee function is available. CAM. AUTO KNEE OFF: Outputs the video signal from the shooting camera.

Set to this position when adjusting the video monitor or when recording the color bar signal. AUTO KNEE function When shooting a foreground subject, such as a human being, etc., with a high-brightness background, if the brightness level is set for the foreground subject, the background image will be blurred with white. In such a case, a clearer background is obtained when the auto knee function is used. It is effective especially in the following cases: • When shooting a human being indoors with a view to the landscape out through a window. • When shooting a human being in the shade on a fine day. • When shooting a high-contrast scene. CAUTION: If a fast moving high-brightness section like a car in sunlight is shot, the auto knee function may change the brightness of the entire image along with the motion of the object. In this case, set the auto knee function to OFF. @ [WHT.BAL] White balance switch Three white balance modes are selectable with this switch. B : If white balance is performed with the switch in this position, it will be memorised into B. A : If white balance is performed with the switch in this position, it will be memorised into A. PRST (PRESET) : A non-erasable white balance setting at 3200K. • FAW (Full-time Auto White) mode can be set to A, B or PRESET with the OPERATION MENU (see page 73). In the FAW mode, video color temperatures are constantly sampled for automatic adjustment to a proper white balance. # [NG] button Pressing this button while recording or in the record-pause mode deletes the S.S.F. data stored in the memory of the GY-DV500 with the S.S.F.
