What Is WDR in Video Camera?

If you’re in the market for a new video camera, you may have come across the term “WDR.” But what exactly is WDR and why is it important? In this article, we’ll take a closer look at what WDR is and how it can benefit you.

What Is WDR?

WDR stands for “Wide Dynamic Range.” In simple terms, it refers to a video camera’s ability to capture details in both bright and dark areas of a scene. This is important because when there is a large difference in brightness between the foreground and background of a shot, traditional cameras may struggle to capture both areas properly.

How Does WDR Work?

WDR works by capturing multiple images of the same scene with different exposure levels. These images are then combined to create one final image that has details in both bright and dark areas. This process is called “tone mapping.”

For example: Imagine you’re filming a person standing in front of a bright window. Without WDR, either the person’s face would be too dark or the window would be too bright and overexposed. But with WDR, multiple images are taken at different exposures so that both the person’s face and the window can be properly exposed.

Why Is WDR Important?

WDR is important because it allows you to capture more detail in your videos. It can be especially useful in situations where there are extreme differences in brightness within a scene, such as shooting outdoors on a sunny day or filming inside with bright lights.

In addition to capturing more detail, WDR can also make your videos look more professional. By properly exposing all areas of your shot, your footage will have a more polished look that will impress your viewers.

Types of WDR

There are two main types of WDR: “digital WDR” and “true WDR.”

Digital WDR: This type of WDR uses software to combine multiple images into one. While it can improve the dynamic range of your footage, it’s not as effective as true WDR.

True WDR: True WDR uses a specialized image sensor that can capture multiple images at different exposures simultaneously. This results in a much more accurate and detailed final image.


If you’re looking for a video camera that can capture more detail in your footage, then you should definitely consider getting one with WDR. With its ability to properly expose both bright and dark areas of a scene, you’ll be able to create more professional-looking videos that will impress your viewers. And if you want the best possible results, make sure to look for a camera with true WDR technology.
