With its realistic images HDR-TV provides an outstanding user experience for the viewers. In the HDR-TV production process certain conversions have to be done, like
Convert your camera log based HDR content into HLG or PQ.
Mix your HDR content with different HDR or SDR content.
Create a SDR version.
LUTs (Look Up Tables) are the secret ingredient for those conversions.
For the best possible viewing experience, it is important to understand what a LUT does and how to evaluate LUTs and choose the right one for your workflow in live or post production.
