WDR/DNR

When both high-brightness subjects and low-brightness subjects need to be displayed at the
same time, overexposure in the high-brightness areas or a loss of dark detail in the low-
brightness areas may occur. The WDR (Wide Dynamic Range) function creates images free
from over-exposure or loss of dark detail by combining two images from tripping the shutter
for a long exposure time and for a short exposure time in one field. The DNR (Digital Noise
Reduction) function creates 'noiseless' images, even in low light. In 'WDR on' mode, unnatural

avoid using the WDR function. To set WDR and DNR settings:
