7.5.6WDR/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 color or image, and noise, may occur in a bright area. Under special illumination, it is better to avoid using the WDR function. To set WDR and DNR settings:
1.From the MAIN MENU, select CAMERA SETUP. The submenu CAMERA SETUP appears.
2.Select WDR/DNR. The screen WDR/DNR appears.
