while the AGC switch is on increases gain by up

When switched on, this function adjusts exposure
to compensate for situations where the subject is
lit from behind.
NOTE: When the BLC is in the “ON” posi-
tion, hunting may occur; that is, the image may
get darker and lighter as the camera “hunts”
for the best exposure level. If hunting occurs,
set the BLC switch to “OFF”.

tion automatically adjusts the shutter speed to main-
tain a suitable exposure level. Set switch to OFF if

matically adjusts white balance to suit special light-
ing sources such as sodium lamps.
