HDR stands for High Dynamic Range, which is a technology that can improve the quality of video and photography by expanding the range of contrast and color beyond what is possible with traditional media standards. HDR video contains more data to describe brightness and color across a much wider range, allowing HDR-capable displays to show an image built from a wider gamut of color and brightness. HDR photography involves capturing multiple frames of the same scene with different exposures and then combining them into one image with a higher dynamic range than those of individually captured frames. Here are some key points about HDR:

• HDR can push video content past the limitations of traditional media standards, resulting in deeper, richer colors and brighter highlights.
• HDR expands the range of both contrast and color significantly, allowing bright parts of the image to get much brighter and colors to show more bright blues, greens, reds, and everything in between.
• HDR is available in numerous formats, including HDR10, Dolby Vision, HDR10+, and HLG.
• HDR content requires an HDR-compatible display to be viewed properly.
• HDR photography involves capturing multiple frames of the same scene with different exposures and then combining them into one image with a higher dynamic range than those of individually captured frames.

In summary, HDR is a technology that can improve the quality of video and photography by expanding the range of contrast and color beyond what is possible with traditional media standards.
