[pure-silver] Re: Shoulder and highlight

I don't think this is correct.

Image gradation, and consequently, every final print tone depends purely on
the combination of film and paper characteristics. This is best visualized
in the typical tonal reproduction cycle, where one quadrant is occupied by
the film and another by the paper characteristic curves.

A film with a mid-tone 'hump' will make for lighter mid-tones in the final
print than a straight-line film characteristic on the same paper (Tmax is
such an example). This means two films with similar highlight
characteristics can have quite different mid-tone characteristics.
