wdr (wide dynamic range)

Short for Wide Dynamic Range. Allows for clear image where lighting demands or lighting range varies. Cameras typically used when directed toward large window or entrance door -- large amounts of light will effect image. Without WDR, images may appear washed out, subjects extremely dark. Uses two shutter speeds (high normal) for alternate images, combines two into one frame for clear, detailed picture. Digital Wide Dynamic Range uses WDR and digital technology.
