  2. High dynamic range - Wikipedia

    en.wikipedia.org/wiki/High_dynamic_range

    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 .

  3. Multi-exposure HDR capture - Wikipedia

    en.wikipedia.org/wiki/Multi-exposure_HDR_capture

    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.

  4. High-dynamic-range rendering - Wikipedia

    en.wikipedia.org/wiki/High-dynamic-range_rendering

    The use of high-dynamic-range imaging (HDRI) in computer graphics was introduced by Greg Ward in 1985 with his open-source Radiance rendering and lighting simulation software which created the first file format to retain a high-dynamic-range image. HDRI languished for more than a decade, held back by limited computing power, storage, and ...

    en.wikipedia.org/wiki/Tone_mapping

    Tone mapped high-dynamic-range (HDR) image of St. Kentigerns Roman Catholic Church in Blackpool, Lancashire, England, UK. Tone mapping is a technique used in image processing and computer graphics to map one set of colors to another to approximate the appearance of high-dynamic-range (HDR) images in a medium that has a more limited dynamic range.

  6. High-dynamic-range television - Wikipedia

    en.wikipedia.org/wiki/High-dynamic-range_television

    High-dynamic-range television (HDR-TV) is a technology that uses high dynamic range (HDR) to improve the quality of display signals. It is contrasted with the retroactively-named standard dynamic range (SDR). HDR changes the way the luminance and colors of videos and images are represented in the signal and allows brighter and more detailed ...

  7. Dynamic range - Wikipedia

    en.wikipedia.org/wiki/Dynamic_range

    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. Tone mapping maps the image differently in shadow and highlights in order to better distribute the lighting range across the image.
