Isn't that just BT.2100?
- turnsout 3y agoYeah, it does appear to be a reiteration of Rec. 2100 / BT.2100. I wonder if it's because this refers to still images rather than video?
- altairprime 3y agoYes, that’s why: https://stage.color.org/hdr/07-Nicolas_Bonnier.pdf https://stage.color.org/hdr/07-Nicolas_Bonnier.pdf (slide “Motivations”): > Several attempts to use PQ/HLG and BT.2020 for still photography are surfacing > But so far, the digital still imaging industry has not settled on a reference HDR/WCG image encoding for consumers > The purpose of TS 22028-5 is to provide requirements and guidelines for HDR/WCG colour encoding of still images And a bit further down, referring specifically to BT.2100: > Shall use ITU-R BT.2020/2100-2 colour primaries
