Many cameras (in my case the Nikon Z6iii, Z8, and Z9) support HLG images.
HLG images have a significantly different histogram. It would be great to have C1 support HLG (maybe as a base characteristic when it finds the HLG tag) to apply an acceptable curve.
Also, This would impact the culling feature as right not HLG images look muddy in the culling processor.
Current workaround
I either use another tool... In a pinch, I also have some presets saved.
