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

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 3-12. The wide dynamic level
ranges from 0 to 100.
Note:
This function varies depending on different camera models.
