LUTs (Look Up Tables) in HDR-TV (post-)production
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.
