High dynamic range (HDR) is a photography term that describes media applications such as digital imaging and digital audio production. The HDR feature is capable of producing a higher dynamic range than the status quo.

Digital imaging

  • High-dynamic-range imaging (HDRI), the compositing of images or videos to extend the dynamic range beyond the native capability of the capturing device
  • High-dynamic-range rendering (HDRR), the real-time rendering of virtual environments using a dynamic range of 65,535:1 or higher (used in computer technology)

Digital audio

  • XDR (audio): Used to provide higher-quality audio when using microphone sound systems or recording into cassette tapes
  • HDR Audio: a dynamic mixing technique used in EA Digital Illusions CE Frostbite Engine to allow relatively louder sounds to drown out softer sounds
