HDR

High Dynamic Range (HDR) for video is a technology that enhances the visual quality of images by expanding the range of color and contrast. Unlike traditional video, which has a limited range of brightness and color representation, HDR video can display a wider spectrum of colors and more levels of brightness, from the darkest blacks to the brightest whites. This results in images that are more vibrant, realistic, and closer to what the human eye naturally perceives in the real world.

HDR accomplishes this by using a greater bit depth per color, which allows for more shades of each primary color and thus a broader overall color palette. Additionally, HDR video can reach higher levels of brightness, enhancing the contrast between light and dark areas of the picture. This increased contrast brings out more detail in both the shadows and highlights, revealing subtleties that would otherwise be lost in standard dynamic range (SDR) video.

The impact of HDR on the viewer's experience is significant. It brings a more lifelike, immersive quality to the content, making images pop and appear more three-dimensional. However, to fully appreciate HDR content, it's necessary to have an HDR-compatible display and a source that provides HDR video, such as certain streaming services, UHD Blu-rays, or HDR-capable gaming consoles. As the availability of HDR content continues to grow, it's increasingly becoming a sought-after feature in televisions and other display devices, offering viewers a superior visual experience that takes video quality to new heights.
