Section 2, Chapter F
Colour metrics for chromatic and luminance adaptation (2024), Image part feks

Title: Visual and colourimetric properties for the HDR range;
Changes SDR <-> HDR for 1080 colours and the flower image for the devive (d) output, and with image (i) for eight ambient reflections according to ISO 9241-306
1. Introduction and goals;
2. Some colourimetric properties for the range High Dynamic Range (HDR);
3. Changes SDR <-> HDR for 1080 colours according to ISO 9241-306;
4. Flower image according to ISO 9241-306, and ISO/IEC 15775;
5. Change of Gamma gP in 8 steps according to ISO 9241-306;
6. Equal Gamma change for colour samples and flower image;
7. Applications for an ergonomic image technology for the consumer area.
