High dynamic range (HDR), also known as wide dynamic range, extended dynamic range, or expanded dynamic range, is a signal with a higher dynamic range than usual. The term is often used in discussing the dynamic ranges of images , videos , audio or radio .
High-dynamic-range rendering (HDRR or HDR rendering), also known as high-dynamic-range lighting, is the rendering of computer graphics scenes by using lighting calculations done in high dynamic range (HDR). This allows preservation of details that may be lost due to limiting contrast ratios.
High dynamic range. Techniques that allow a digital image to show a wider contrast range than current image sensors can record in one file. Some cameras have firmware to do the processing. [10] ICM: Intentional camera movement. The camera or the focus or zoom of its lens is adjusted by the photographer during an exposure in order to achieve ...
The term dynamic range may mean: Dynamic range, 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. High-dynamic-range imaging, the intention of HDRI is to represent the wide range of intensity levels found in real scenes.
Tone mapped high-dynamic-range (HDR) image of St. Kentigern's Church in Blackpool, Lancashire, England. In photography and videography, multi-exposure HDR capture is a technique that creates high dynamic range (HDR) images (or extended dynamic range images) by taking and combining multiple exposures of the same subject matter at different exposures.
EasyHDR is a High Dynamic Range (HDR) image processing software that merges differently exposed photographs into HDR radiance map and tone maps them. With a single photograph, easyHDR can be used to increase contrast and refresh colors (LDR enhancement mode).
Though this does not increase the fixed dynamic range available at the film or sensor, it stretches usable dynamic range in practice. [55] High-dynamic-range imaging overcomes the limited dynamic range of the sensor by selectively combining multiple exposures of the same scene in order to retain detail in light and dark areas.
High dynamic range, a general term describing dynamic range across multiple fields; High-dynamic-range video, a technology related to HDR displays and formats such as HDR10, Dolby Vision, HDR10+, and others.
