If you are familiar with our old LUT Generator: “ALEXA Classic 709” is the well-known K1S1 LUT.
For HDR you can set the Peak White Point: 1000, 2000 or 4000 nits. The 3D LUTs are based on different tone-mapping curves depending on the maximum luminance.
When switching both monitor and camera from an 1000 PQ LUT to the respective 1000 HLG LUT, the displayed image should look identical.
We provide 3D LUTs that render diffuse white towards an approximate luminance of 100 or 200 cd/m2. The 3D LUTs rendering diffuse white towards 200 cd/m2 are compatible with the BBC recommendations for creating HLG compatible HDR signals.
