Sometimes when you want to take a picture under a very bright light, the subject you want to focus on will turn out to be vague due to the intense back light surrounding it. Now, you can solve this problem by using the WDR camera. WDR refers to the wide dynamic range function of a camera. With this function, the camera is able to take clearer images than normal camera, especially under back light circumstances where intensity of illumination can vary excessively.
For instance, when there are both very bright and very dark areas simultaneously in the field of view of the camera. WDR enables the capture and display of both bright and dark areas in the same frame.
WDR camera is also commonly used in surveillance cameras and in some medical applications. In surveillance, WDR allows a camera to filter the intense back light surrounding a subject and thus enhances the ability to distinguish features and shapes on the subject.
