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:
“Ay, look: high heaven and earth ail from the prime foundation;
All thoughts to rive the heart are here, and all are vain:
Horror and scorn and hate and fear and indignation—
Oh, why did I awake? When shall I sleep again?”
—A.E. (Alfred Edward)
“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)
“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)
