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:
“A lunatic may be “soothed,”... for a time, but in the end, he is very apt to become obstreperous. His cunning, too, is proverbial, and great.... When a madman appears thoroughly sane, indeed, it is high time to put him in a straight jacket.”
—Edgar Allan Poe (1809–1849)
“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)
“Lord Bateman prepared for another marriage,
So both their hearts so full of glee.
‘I will range no more to foreign countries
Now since Sophia have a-crossed the sea.’”
—Unknown. Young Beichan (l. 81–84)
