10.2.9 BLC
If you focus on an object against a strong backlight, the object will be too dark to be seen clearly. BLC
(backlight compensation) compensates light to the object in the front to make it clear. If BLC mode is set
to Custom, you can draw a red rectangle on the live view image as the BLC area.
10.2.10 WDR
The WDR (Wide Dynamic Range) function helps the camera provide clear images in environment with
strong illumination differences.
When there are both very bright and very dark areas simultaneously in the field of view, you can enable
the WDR function and set the level. WDR automatically balances the brightness level of the whole image
and provides clear images with more details.
When WDR is enabled, some other functions may be not supported. Refer to the actual
interface for details.

White balance is the white rendition function of the camera. It is used to adjust the color temperature
according to the environment.

Digital Noise Reduction is used to reduce image noise and improve image quality. Normal and Expert modes
are selectable.
Normal: Set the DNR level to control the noise reduction degree. A high level means strong reduction.
Expert: Set the DNR level for both space DNR and time DNR to control the noise reduction degree. A high
level means strong reduction.

details so that the image appears clearer.
