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:
“They talk about their Pilgrim blood,
Their birthright high and holy!
A mountain-stream that ends in mud
Methinks is melancholy.”
—James Russell Lowell (1819–1891)
“The nearer a conception comes towards finality, the nearer does the dynamic relation, out of which this concept has arisen, draw to a close. To know is to lose.”
—D.H. (David Herbert)
“The Canadians of those days, at least, possessed a roving spirit of adventure which carried them further, in exposure to hardship and danger, than ever the New England colonist went, and led them, though not to clear and colonize the wilderness, yet to range over it as coureurs de bois, or runners of the woods, or, as Hontan prefers to call them, coureurs de risques, runners of risks; to say nothing of their enterprising priesthood.”
—Henry David Thoreau (1817–1862)
