This has become a point of significant confusion among consumers, whereby HDR and WCG are either confused for each other or treated as interchangeable. The color dynamism and wider range of colors frequently attributed to HDR video is actually a consequence of a Wide Color Gamut (WCG). The colorful parts of the image can be even more colorful (if WCG is used). the darkest parts of an image) can be darker and more detailed. The larger capacity for brightness can be used to increase the brightness of small areas without increasing the overall image's brightness, resulting in, for example, bright reflections from shiny objects, bright stars in a dark night scene, and bright and colorful light-emissive objects (e.g. the brightest parts of an image) can be brighter, more colorful, and more detailed. No current display is able to reproduce the maximal range of brightness and colors that can be represented in HDR formats. The benefits of HDR depend on the display capabilities, which vary. They can constrain themselves to the limits of SDR even if the content is delivered in an HDR format. Content creators can choose to what extent they make use of HDR capabilities. HDR contents are often limited to a peak brightness of 1000 or 4000 nits and P3-D65 colors, even if they are stored in formats capable of more. In practice, HDR is not always used at its limits.
709/ sRGB gamut, while common HDR formats use Rec. The most common SDR formats are limited to the Rec. darker) black levels and more saturated (i.e. HDR also enables the representation of lower (i.e. For HDR, this number goes up to at least 1000 nits, and in some cases up to 10,000 nits. SDR formats are able to represent a maximum luminance level of around 100 nits. Standard dynamic range (SDR) is still based on, and limited by, the characteristics of older cathode ray tubes (CRT), despite the huge advances in screen and display technologies since CRT's obsolescence. By contrast, HDR improves the perceived fidelity of the existing individual pixels themselves. 1.1.1 Preservation of content creator intentīefore HDR, improvements in the fidelity of displays were typically achieved by increasing the pixel quantity and density (resolution) and the display's frame rate.2100 and all common HDR formats require HDR to be delivered with wide color gamuts (WCG). Beside dynamic range, HDR-TV also improves color gamut as Rec. HDR-TV is a part of HDR imaging, an end-to-end process of increasing the dynamic range of images and videos from their capture and creation, to their storage, distribution and display. It is now also available for still pictures. HDR-TV was first used in 2014 to enhance videos. Not all HDR displays have the same capabilities, and HDR content will thus look different depending upon the display used. It does not improve a display's intrinsic properties (brightness, contrast, and color capabilities). HDR allows compatible displays to receive a higher quality image source. It allows representing brighter and more detailed highlights, darker and more detailed shadows, and a wider array of more intense colors. HDR changes the way the luminance and colors of videos and images are represented in the signal. It is contrasted with the retroactively-named standard dynamic range (SDR). High-dynamic-range television ( HDR or HDR-TV) is a technology that improves quality of display signals.
