Lut range for lutcalc9/28/2023 ![]() Aims to contain the YPbPr of the output to within the display's range (Rec709/sRGB or Rec2020) when going from a wide gamut to a narrower one, even if the luminance is above legal and extended. New Feature - Batch-generate sets of exposure compensation LUTs across a user-selectable EI range and step size.Feature Removal - ALEXA-X-2 Gamut until I have reanalysed the tone map used.Bugfix - Fixed issue in Mac App where white balances could not be taken from the CIE xy / uv preview image.Bugfix - Fixed 'Print Chart' bug from the last update.Feature Change - Reanalysed BMDFilm and BMDFilm4k Gamma.New Feature - RGB Sampler for sampling multiple points on preview images.New Feature - BBC 0.4, 0.5 and 0.6 Gammas.New Feature - Canon EOS Standard Gamma (plus a version scaled to within legal range).Bugfix - BMD4.6kFilm Gamma output range.Bugfix - Reanalysed RED Gamma 4 against RED's 1D LUTs.New Feature - Bolex Log and Bolex Wide Gamut.New Feature - RED Gamma 1 and RED Gamma 2 using data from.Bugfix - Gamut Limiter tool was blocking LUT generation.Bugfix - Fixed Javascript policies which stopped LUTCalc working on Internet Explorer / Edge browser.Feature Change - Improved interpretation of Canon EOS Standard and Normal gammas.Feature Change / Bugfix - Extensive rewrite of 'Custom Colour Space' code.Feature Change - New code for estimating the gamut triangle on the 'xy / uv chromacity' preview.Feature Change - Reworked 1D interpolation code for speed and efficiency.Feature Change - Extensive rewrite of LUTAnalyst code for improved accuracy.Feature Change - Complete rewrite of 3D interpolation / extrapolation code for efficiency, accuracy, clarity and maintainability. ![]() New Feature - Custom Colour Space can now set primaries from a matrix and white point / illuminant.New Feature - 'DaVinci Resolve 12+ auto' preset option, to reflect that Resolve 12's default 'auto' clip range setting.Where LUTs appear to have been clamped (ie the maximum output value is exactly 1.0 and or the minimum exactly 0.0), the declip process will attempt to extrapolate the clipped values, then limit them within a sensible range without hard clipping. New Feature - 'Declip' button on the LUTAnalyst tool.Clicking it creates a LUT title containing input and output gamma and gamut details, plus basic info of customisation (currently black level and saturation). New Feature - Sony Standard Gammas STD 1-6.New Feature - P3 Colourspace now available with DCI, D60 and D65 white points.Legalises colours and fixes potential LUT overshoots when going from a wide Gamut such as S-Gamut3 to a narrow one such as Rec709. New Feature - Completely new gamut limiter algorithm and code.New Feature - Choice of tricubic, tetrahedral and trilinear interpolation for analysis and use in LUTAnalyst.
