  2. Blend modes - Wikipedia

    en.wikipedia.org/wiki/Blend_modes

    The Luminosity blend mode preserves the hue and chroma of the bottom layer, while adopting the luma of the top layer. Because these blend modes are based on a color space which is much closer than RGB to perceptually relevant dimensions, it can be used to correct the color of an image without altering perceived lightness , and to manipulate ...

  3. HSL and HSV - Wikipedia

    en.wikipedia.org/wiki/HSL_and_HSV

    Fig. 1. HSL (a–d) and HSV (e–h). Above (a, e): cut-away 3D models of each. Below: two-dimensional plots showing two of a model's three parameters at once, holding the other constant: cylindrical shells (b, f) of constant saturation, in this case the outside surface of each cylinder; horizontal cross-sections (c, g) of constant HSL lightness or HSV value, in this case the slices halfway ...

  4. Gamma correction - Wikipedia

    en.wikipedia.org/wiki/Gamma_correction

    "Luminance" can mean several things even within the context of video and imaging: luminance is the photometric brightness of an object (in units of cd/m 2), taking into account the wavelength-dependent sensitivity of the human eye (the photopic curve); relative luminance is the luminance relative to a white level, used in a color-space encoding;

  5. HCL color space - Wikipedia

    en.wikipedia.org/wiki/HCL_color_space

    Luminance (Y or L v,Ω) The radiance weighted by the effect of each wavelength on a typical human observer, measured in SI units in candela per square meter ( cd/m 2 ). Often the term luminance is used for the relative luminance , Y / Y n , where Y n is the luminance of the reference white point .

  6. Adobe RGB color space - Wikipedia

    en.wikipedia.org/wiki/Adobe_RGB_color_space

    Moreover, the black point shall have the same chromaticity as the white point, yet with a luminance equal to 0.34731% of the white point luminance. [4] The ambient illumination level at the monitor faceplate when the monitor is turned off must be 32 lx. As with sRGB, the RGB component values in Adobe RGB (1998) are not proportional to the ...

  7. CIELAB color space - Wikipedia

    en.wikipedia.org/wiki/CIELAB_color_space

    HCL color space (Hue-Chroma-Luminance) on the other hand is a commonly used alternative name for the L*C*h(uv) color space, also known as the cylindrical representation or polar CIELUV. This name is commonly used by information visualization practitioners who want to present data without the bias implicit in using varying saturation.
