High Dynamic Range, or HDR, is a technology used in photography, video, and displays that enhances the contrast between the brightest and darkest parts of an image. This results in more vivid colors and greater detail in shadows and highlights, making the visual experience more lifelike. HDR content is designed to take advantage of displays that support this technology, allowing viewers to see a wider range of brightness levels. HDR can be found in various formats, such as HDR10, Dolby Vision, and HLG, each with its own specifications and capabilities. Many modern televisions, monitors, and streaming services support HDR, providing users with an improved viewing experience. As a result, HDR has become increasingly popular in both home entertainment and professional media production.
