In practice, HDR is not always used at its limits. HDR contents are often limited to a peak brightness of 1,000 or 4,000 nits and P3-D65 colors, even if they are stored in formats capable of more. [7] [8] Content creators can choose to what extent they make use of HDR capabilities. They can constrain themselves to the limits of SDR even if the ...
High dynamic range (HDR), also known as wide dynamic range, extended dynamic range, or expanded dynamic range, is a signal with a higher dynamic range than usual. The term is often used in discussing the dynamic ranges of images , videos , audio or radio .
Dolby Vision is a set of technologies developed by Dolby Laboratories for high dynamic range (HDR) video.
