Lutcalc wont load settings5/17/2023 ![]() ![]() Feature Change - More flexible PQ selection.Bugfix - Fixed initial black clip / white clip bounds on the stop chart not displaying.Bugfix - fixed slight offset to x-axis in LUT in / LUT out chart.Feature Change - Hypergammas 7 & 8 plus Rec709 (800%) have been recalculated along withe the other Hypergammas for precision.Not an ideal situation, but can be used to reverse an accidentally burnt-in LUT in CineEI mode. New Feature - Rec709(800%) with black at 3% (the built-in LUT in Sony CineEI mode) is now included as an input gamma option.New Feature - All Sony Hypergammas (1-8) plus Cinegammas 1 and 2 are now included (HG4 is also the same as Cinegamma 1, HG2 the same as Cinegamma 2).New Feature - Provisional SmallHD preset based on SmallHD feedback - pending confirmation.Feature Change - Improved / more robust gamma reversal code for LUTAnalyst.Bugfix - typo meant that SPI3D files were generated without the mesh sizes.Bugfix - xy/uv gamut outlines were failing for LUTAnalyst colourspaces.Feature Change / Provisional Bugfix - changed the way that Dolby PQ is scaled due to user feedback.Feature Change - Linear and conventional gamma options are now listed under 'Linear / γ' rather than 'Linear / Rec709' to avoid confusion.Feature Change - added 14-bit (16384 point) output option to 1D cube files.Feature Change - Improved flexibility in preset range settings for particular curve / format combinations. ![]() Feature Change - Improved luminance coefficient calculation from colourspace primaries.Feature Change - Improved LogC calculations from Arri's ACES IDTs.New Feature - ProPhoto / ROMM RGB colourspace and gamma.New Feature - Experimentally-derived DJI D-Log gamma for Zenmuse X3 / Osmo.New Feature - Alexa Classic 709 (Alexa-X-2) gamma and gamut.New Feature - LUTAnalyst automatically sets output gamma and gamut to the analysed LUT.New Feature - Print out the Stop vs IRE chart, plus exposure table and IRE / 10-bit values for each stop from -8 to +8.Bugfix - When using LUTAnalyst, the preview window was not automatically updating to reflect the analysed colour gamut.New Feature - Panasonic GH4 V-Log camera option.New Feature - REDWideGamutRGB and Log3G10.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. ![]()
