Description
English: This is the Luma (Y′) of the original image Fire_breathing_2_Luc_Viatour.jpg, which shows the Fire breathing "Jaipur Maharaja Brass Band", Chassepierre, Belgium. Y′ has been calculated using the weightings from Rec. 601. Since sRGB does not use NTSC primaries, this is actually an incorrect calculation of Luma, which should use Rec. 709 weightings instead, but it is the calculation Adobe Photoshop uses for its “Luminosity”, “Color”, “Hue”, and “Saturation” blend modes, regardless of an RGB image’s color space.
