Backlight Settings
 BLC (Back Light Compensation)
If there’s a bright backlight, the subject in front of the backlight appears silhouetted or dark.
Enabling BLC(back light compensation) function can correct the exposure of the subject. But
the backlight environment is washed out to white.
 WDR (Wide Dynamic Range)
The wide dynamic range (WDR) function helps the camera provide clear images even under
back light circumstances. When there are both very bright and very dark areas
simultaneously in the field of view, WDR balances the brightness level of the whole image
and provide clear images with details.
You can enable or disable the WDR function as shown in Figure 7-30. The wide dynamic
level ranges from 0 to 100.
