Dynamic range is a term used frequently in numerous fields to describe the ratio between the smallest and largest possible values of a changeable quantity.
Examples of usage
Audio engineers often use dynamic range to describe the ratio of the loudest possible relatively-undistorted sound to silence or the noise level, say of a microphone or loudspeaker. In digital audio, the maximum possible dynamic range is given by the bit resolution.
Electronics engineers apply the term to:
In music, dynamic range is the difference between the quietest and loudest volume of an instrument, part or piece of music.
Photographers use dynamic range as a synonym for the luminosity range of a scene being photographed; the light sensitivity range of photographic film, paper and digital camera sensors; the opacity range of developed film images; the reflectance range of images on photographic papers.
High Dynamic Range Imaging is a rendering technique for computer graphics to make images appear more vibrant and make lighting more accurate to the way real light is perceived by the eye.
