High Dynamic Range, or HDR, is a technology that enhances the contrast and color range in images and videos. It allows for a greater difference between the darkest and brightest parts of an image, making details more visible in both shadows and highlights. This results in a more realistic and vibrant viewing experience. HDR is commonly used in photography, television, and gaming. By capturing and displaying a wider spectrum of colors and brightness levels, HDR content appears more lifelike. Many modern devices, such as smartphones and 4K TVs, support HDR to provide users with improved visual quality.
