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 5-32. The wide
dynamic level ranges from 0 to 100.

This function varies depending on the models of zoom camera.
HLC
HLC (High Light Compensation) makes the camera identify and suppress the strong

of the image that would normally be hidden.
