3. Gamma change gP in 16 steps according to ISO 9241-306;
4. Test files with 3, 5, 9, 17, and 33 colour and grey steps;
5. Change of sRGB-pdf files for the display range HDR;
6. Determination of visual Gamma with 3, 5, 9, 17, and 33 colour steps;
7. Specifiction of the image quality with the regularity index g* according to ISO/IEC 15775;
8. Increase of the image quality with colourimetric or visual Gamma;
9. Applications for an ergonomic image technology for the consumer area.
