>SDR should be mapped into HDR as when played in a reference environment, the composited result should then be adapted to the viewing environment. (Which in a bright environment means that both HDR and SDR are made brighter.) >If this conclusion is completely incorrect, then I should just scrap the document instead of working on fixing the inaccuracies. Fredrik, Maybe I missed it, but I have not seen any study that confirms this approach. SDR devices have unpredictable shadow rendering due to a wide range of black levels across devices. Some colorists intentionally lift blacks to avoid loss of shadow details. HDR devices are expected to provide dark blacks, and often render SDR blacks darker than intended. So a trivial mapping of SDR to HDR might not preserve the creative intent for SDR. Is there a study on this?
