The idea is that these will allow people to view the output of the gamut mapper through a variety of display transforms, and therefore hopefully judge its affect on image appearance in a way which is not tied to the ACES Output Transform. We want to avoid making “corrections” to the behaviour of the gamut mapper to compensate for e.g. hue skewing which is in fact a result of the display transform.
I hope that the names of the BLG files are self-explanatory.
These can be used in Baselight for Nuke in free mode. This does require a Nuke license, as Nuke Non-Commercial does not support 3rd party plugins.
- Use a Baselight node as your View Transform. Nuke’s VLUT should therefore be set to None or RAW.
- Chose from blg for both set input colour space and set output colour space.
- Chose one of the BLG files in the blg file field.
- Confirm that once the BLG has loaded, input colour space is set to ACEScg: Linear / AP1 and output colour space is set to Rec.1886: 2.4 Gamma / Rec.709.
- Change output colour space if required for your display to sRGB: ~2.2 Gamma / Rec.709 or Apple: ~2.2 Gamma / P3 D65 (Apple Display P3).
Your node tree should now look something like this:
