Section 2, Chapter G
Equally spaced colour scales for optimal colour-image quality (2025), Image part gews

Title: Adjacent and separate grey samples for interval scaling;
Series N-W, and dark and light N-W scales;
Four surrounds mean Grey U=N08w, dark Grey D=N04w, light Grey H=N12w, and darker mean Grey d=N06w.
1. Introduction and goals.
2. Visual 3, 5 or 9-step intervall scaling;
3. Visual samples on surrounds U, D, H, and d;
4. Visual numeric specification and calculation of scaling with example.
5. Application for the linearisation of the scales with inverse functions.
Remark: For similar test charts see gels.htm.

The following ten pages gew0 to gew9 of this chapter
show the content with links to the single figures in up to six formats.
