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:
“To me this world is all one continued vision of fancy or imagination, and I feel flattered when I am told so. What is it sets Homer, Virgil and Milton in so high a rank of art? Why is Bible more entertaining and instructive than any other book? Is it not because they are addressed to the imagination, which is spiritual sensation, and but mediately to the understanding or reason?”
—William Blake (1757–1827)
“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)
“A girl must allow others to share the responsibility for care, thus enabling others to care for her. She must learn how to care in ways appropriate to her age, her desires, and her needs; she then acts with authenticity. She must be allowed the freedom not to care; she then has access to a wide range of feelings and is able to care more fully.”
—Jeanne Elium (20th century)
