The nonlinear relations for L* , a* , and b* are intended to mimic the nonlinear response of the eye.
Thank you for pointing me to this. I had ignored it. So is there a way to get the RAW values with applied exposure compensation in RT?
We should describe how to examine raw values in RawPedia, and describe what those values mean (i.e. are they before or after black level subtraction, etc).

I ask this question because I want to adapt a DCP to ETTR (expose to the right): I overexpose a photo under a fixed light source and after that must compensate for this in the RAW converter with a fixed negative EV. But then I need to adapt the tonecurve, too, because high values may be still too light, and low values will be too dark. I need to now how I can make a transformative tonecurve so that all tones will be correct with a fixed baseline exposure offset.
