High-dynamic-range video

High-dynamic-range video (HDR video) describes video having a dynamic range greater than that of standard-dynamic-range video (SDR video). HDR video involves capture, production, content/encoding, and display. HDR capture and displays are capable of brighter whites and/or deeper blacks. To accommodate this, HDR encoding standards allow for a higher maximum luminance and use at least a 10-bit dynamic range (compared to 8-bit for non-professional and 10-bit for professional SDR video) in order to maintain precision across this extended range.

While technically 'HDR' refers strictly to the ratio between the maximum and minimum luminance, the term 'HDR video' is commonly understood to imply wide color gamut as well. In February and April 1990, Georges Cornuéjols introduced the first real-time HDR camera combining two successively or simultaneously-captured images.
