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:
“Were I as base as is the lowly plain,
And you, my Love, as high as heaven above,
Yet should the thoughts of me, your humble swain,
Ascend to heaven in honour of my love.”
—Joshua Sylvester (1561–1618)
“Magic is the envelopment and coercion of the objective world by the ego; it is a dynamic subjectivism. Religion is the coercion of the ego by gods and spirits who are objectively conceived beings in control of nature and man.”
—Richard Chase (b. 1914)
“Compared to football, baseball is almost an Oriental game, minimizing individual stardom, requiring a wide range of aggressive and defensive skills, and filled with long periods of inaction and irresolution. It has no time limitations. Football, on the other hand, has immediate goals, resolution on every single play, and a lot of violence—itself a highlight. It has clearly distinguishable hierarchies: heroes and drones.”
—Jerry Mander, U.S. advertising executive, author. Four Arguments for the Elimination of Television, ch. 15, Morrow (1978)
