What is WDR? Wide Dynamic Range (WDR) technology
Wide Dynamic Range (WDR) technology uses two shutter speeds in alternative video fields, high and normal, and combines these two fields into one frame. It allows every detail to be captured accurately even if one portion is bright while other portions are dark. As a result, combined fields yield a frame of high quality images. Below is a comparison of camera technologies with its video images of Regular, Back-light Compensation (BLC), and Wide Dynamic Range.
