Title: Colour loop, contrast steps according to ISO 9241-306,
image-output quality by regularity index g* according to ISO/IEC 15775
1. Introduction and goals.
2. Colour loop: ISO file - print output - scan or camera input - ISO file.
3. Contrast steps CYP1 to CYP8 according to ISO 9241-306:2018.
4. Images with raw data rgb and linearized data rgb*.
5. Image-output quality by the regularity index g* according to ISO/IEC 15775:2022.
6. 7 sets of image data and regularity indices between under and over exposure for slide and negative film.
7. ISO image with 4 resolutions for slide and negative film.
8. Discussion of image quality.

The following ten pages eeb0 to eeb9 of this chapter
show the content with links to the single figures in up to six formats.
