solarized. This is normal for WDR, and is not a camera malfunction. This function is only available

Visibility Enhancement: (OFF/Low/Middle/High) Images in foggy or rain environments or in
environments with a very strong luminous intensity have a dynamic range that is significantly
lower than ordinary images. The user can use this Visibility Enhancement setting to "DEFOG" the


Settings (AE) field. This option is useful when the bright highlights, such as flashlight or car
