BLC

If you focus on an object against strong backlight, the object will be too dark to be seen clearly. BLC

(backlight compensaon) compensates light to the object in the front to make it clear. If BLC mode

is set as Custom, you can draw a red rectangle on the live view image as the BLC area.

HLC

When the bright area of the image is over-exposed and the dark area is under-exposed, the HLC

(High Light Compression) funcon can be enabled to weaken the bright area and brighten the dark

area, so as to achieve the light balance of the overall picture.

WDR

The WDR (Wide Dynamic Range) funcon helps the camera provide clear images in environment

with strong illuminaon dierences.

When there are both very bright and very dark areas simultaneously in the eld of view, you can

enable the WDR funcon and set the level. WDR automacally balances the brightness level of the

whole image and provides clear images with more details.

Note

When WDR is enabled, some other funcons may be not supported. Refer to the actual interface

for details.
