High Dynamic Range (HDR) is a technology used in imaging and photography to enhance the quality of a picture by increasing its dynamic range—the contrast between the darkest blacks and the brightest whites. It aims to produce images that closely resemble how human eyes perceive light and color in real life.

HDR10 is an open standard supported by major manufacturers and often considered the baseline for HDR content. It uses static metadata, which means it applies one set of data to the entire movie or show. This metadata informs the display how to handle color and brightness levels up to a maximum of 1,000 nits (a unit of brightness). HDR10 uses a 10-bit color depth, which allows for 1,024 shades of each primary color and about a billion total colors.

Dolby Vision is a more advanced form of HDR created by Dolby Laboratories. Contrary to HDR10’s static metadata, Dolby Vision uses dynamic metadata that can adjust brightness and color levels per scene or even per frame, allowing for much more precision and adaptability. This can make a significant visual impact on how content is displayed. Dolby Vision also supports a higher brightness of up to 10,000 nits and potential for 12-bit color depth, equating to over 68 billion colors.

While HDR10 is widely adopted due to its open standard nature, Dolby Vision is often seen as superior due to its dynamic metadata and higher performance capacity. However, Dolby Vision adoption requires licensing; hence it’s not as pervasive as the baseline HDR10 standard. TVs need specific hardware to support Dolby Vision’s advanced features.

In essence, while all these formats aim to enhance viewing experience through improved contrast and color accuracy, Dolby Vision leads in providing the most realistic image that content creators can produce, whereas HDR10 offers substantial improvements over standard dynamic range (SDR) at no additional cost. Consumers choosing between them will have to consider the compatibility of their devices with these formats as well as the type of content they predominantly watch.
