The 24 redundant patches can be put away from the generated. With the standard reference template it8.cht and command scanin -o -dinp scanner.tif it8.cht, rgb values for all the 288 patches would be included in the generated. There are total of 264 patches in Kodak Q60 target. Profile Gamut Volume (absolute intent) recorded with CT3Ĭommand: scanin -o -dinp scanner.tif it8.cht In general, it avoids clipping of values above the white point that can occur in L*a*b* based cLUT input profile.įorces cLUT profile absolute but cLUT white & black points will not be extrapolated with matrix.ĬLUT Lab bsed Profiles, illustrated with Lab co-ordinates, relative rendering and showing white point at L=100 (same scale) This option allows cLUT profile to be created with PCS of XYZ which offers better accuracy for input devices such as displays, scanners and cameras. Profiles that are generated with this option support all the four rendering intents. G = single gamma+matrix, S = single shaper+matrixĭefault option, cLUT profile will be created with PCS of L*a*b*. G = gamma+matrix, s = shaper+matrix, m = matrix only, ![]() L = Lab cLUT (def.), x = XYZ cLUT, X = display XYZ cLUT + matrix ProPhoto primaries have either a* or b* that exceed the -128 to 127 range, as shown below. In reality, those out of range colors are not imaginary but visible and they can be encoded in a PCS of XYZ icc profile. For practical consideration, ICC has imposed L*a*b* encoding range of -128 to +127 for values a* and b*.
