Hi all,
I already posted on Lift Gamma Gain forum but I wish to know more opinions here. I plan to make a new color grading in Dolby Vision (Rec 2020 - P3D65 lmited - PQ curve - 1000 nits) without the licence in DaVinci (still too expensive for rare projects). So no custom trims. I'll have to a make DCP in SDR later from this grading. I'm not used to take HDR sources for this. So I see two options at the moment:
1/ Render a SDR source in Rec 709 - Gamma 2,4 - 100 nits using the Tone Mapping
Pros: Best tone mapping
Cons: Smaller color space
2/ Take the master source in Rec 2020 - P3D65 limited - 1000 nits and then apply a Color Space Transform *
Pros: Bad tone mapping?
Cons: Native color space kept
* not sure about the settings
=> What would you recommend?

During the same conversation on LGG forum, I've been adviced not use my Eizo Prominence in P3D65 - 100 nits for SDR projects... but to stay with Rec 709. I'm a bit surprised because it covers 99% of P3 color space. It is also "compliant" for P3D65 workflows in HDR. So why not SDR? I know tbe Prominence comes with a P3DCI preset at 48 nits but I never work with it because of the white point and the luminance. I use instead a custom preset made by a calibration company in P3D65 - 100 nits - gamma 2,4. I know they could create it in gamma 2,2 as it is usually done for "Display P3" but they argued that it would be better to keep the same EOTF than BT-1886.
=> Do you think I'm going wrong?
Thank you.
