  2. High dynamic range - Wikipedia

    en.wikipedia.org/wiki/High_dynamic_range

    In this context, the term high dynamic range means there is a large amount of variation in light levels within a scene or an image. The dynamic range refers to the range of luminosity between the brightest area and the darkest area of that scene or image. High dynamic range imaging (HDRI) refers to the set of imaging technologies and techniques ...

    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.
