Big Update

  • Guard Rail Implemented with the help of Sakari Kapanen. Guard Rail is designed to keep [0.0, 1.0] domain as is, and only touch the negatives and the above 1.0s, basically, able to replace the Display's Native, while also having wide-gamut handling and chromatic attenuation on the higher side.
  • Replace both pre and post formation compressions with Guard Rails. LUT Resolution and range is still a hard thing to get right, still a bit of banding right now but I have done what I can think of already at the moment.
  • Replace Default Contrast with a 3D formation LUT, basically trying to restore pre-formation chroma angle. I kept 30% of the per channel shifts in there, based on feedback.
  • AgX Log is now from -10 to +15 stops, this is mainly for the new 3D formation LUT to avoid artifacts, but note the formed AgX base is still from -10 stops to +6.5 stops, the same as always, it is only the AgX Log that changed.
  • Two Greyscale Looks got merged. I figured I would use AgX Log as process space, but evaluate the luminance in linear state.
  • Define both ways for some spaces. This way I can skip some non-invertible LUTs in the inverse direction.
