High Dynamic Range

High dynamic range (or HDR for short) is a term generally used for media applications such as digital imaging and digital audio production. It is a feature that is capable of producing a much higher dynamic range than is widely available at the moment.

Applications in 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 65535:1 or higher (used in computer technology)

Applications in digital audio production

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

Famous quotes containing the words high, dynamic and/or range:

    We do not prove the existence of the poem.
    It is something seen and known in lesser poems.
    It is the huge, high harmony that sounds
    A little and a little, suddenly,
    By means of a separate sense. It is and it
    Is not and, therefore, is.
    Wallace Stevens (1879–1955)

    We Americans have the chance to become someday a nation in which all radical stocks and classes can exist in their own selfhoods, but meet on a basis of respect and equality and live together, socially, economically, and politically. We can become a dynamic equilibrium, a harmony of many different elements, in which the whole will be greater than all its parts and greater than any society the world has seen before. It can still happen.
    Shirley Chisholm (b. 1924)

    No doubt, the short distance to which you can see in the woods, and the general twilight, would at length react on the inhabitants, and make them savages. The lakes also reveal the mountains, and give ample scope and range to our thought.
    Henry David Thoreau (1817–1862)
