Backlight compensation OFF
Backlight compensation multifractionated evaluative metering mode (Backlight compensates after
measuring the light of the entire screen.)
Sensitivity settings during Multi BLC
BLC is easier to determine with a larger value (Initial value: 7)
Returns sensitivity during Multi BLC to factory defaults (Initial value: 7)
p: Direct sensitivity settings 0-15 during Multi BLC (Initial value: 7)
Brightness settings during Multi BLC
Larger value increases brightness when determining BLC (Initial value: 7)
Returns brightness settings during Multi BLC to factory defaults (Initial value: 7)
p: Direct brightness settings 0-15 during Multi BLC (Initial value: 7)
BLC center-weighted metering mode (Backlight compensates after measuring the light mainly in the
center.)
Returns sensitivity settings during Center BLC to factory defaults (Each initial value: 0)
p: Top(0-7) q: Bottom(0-7) r: Left(0-7) s: Right(0-7) (Each initial value: 0)
