  2. Color correction - Wikipedia

    en.wikipedia.org/wiki/Color_correction

    Color correction is a process used in stage lighting, photography, television, cinematography, and other disciplines, which uses color gels, or filters, to alter the overall color of the light. Typically the light color is measured on a scale known as color temperature, as well as along a green–magenta axis orthogonal to the color temperature ...

    The use of radiometric units is appropriate to characterize such sensitivity to invisible light. In sensitometric data, such as characteristic curves, the log exposure [4] is conventionally expressed as log 10 (H). Photographers more familiar with base-2 logarithmic scales (such as exposure values) can convert using log 2 (H) ≈ 3.32 log 10 (H).

    This gave cameras equipped with this system the ability to adjust to changes in lighting during the actual exposure which was useful for specialist applications such as photomicrography and astronomical photography. Leica later used a variation of this system, as did Pentax with their Integrated Direct Metering (IDM) in the LX camera. A ...

    The left half shows the photo as it came from the digital camera. The right half shows the photo adjusted to make a gray surface neutral in the same light. In photography and image processing, color balance is the global adjustment of the intensities of the colors (typically red, green, and blue primary colors). An important goal of this ...
