WDR (Wide Dynamic Range) is the technology that adjusts a camera’s image to counter an image that contains both bright and dark areas. Without WDR, the bright areas can be too bright and the dark areas may be too dark, leading to a lack of visibility in those areas. WDR works by capturing multiple images at both a slow and fast shutter speed. The slow speed captures more light and the fast speed captures less. WDR then combines them into a single image. In doing so it brightens the dark spots and darkens the light sports so that the overall image is clearer.
