Attaching an Excel with max LogC4 values computed for each EI and the respective value for ACEScct.

Here is the recording & transcript

So we do not really have a Problem, do we?
Up to ISO 1600-ish LogC4 fits into ACEScct.

And for higher ISOs ACEScct clips a bit in the first stop.
Is this so bad for on-set grading?

I think that ties to a larger question…

In terms of both gamut and encoding curve, is there the mentality that camera data is there to be thrown away? This was my questioning behind the first bullet point of requirements “Camera encoding space”.

Seemingly there is the desire to keep dynamic range information (hence this VWG), but gamut information is on the chopping block?

As a vendor agnostic working space where decisions can be made to handle camera data as needed (RGC for example) I think there is more flexibility in the design of the color space, but if the space is defined as a camera encoding space, putting gamut and dynamic range data in the bin as Step-1 seems counterproductive to me.
