On the default rendering, Vivid added 22 % more chroma than the rendering
itself, and Punch 5 % — less than the photographer's earlier exports show
with no look applied (14 % over ours) and well below their everyday look
(27 %). Each preset's colour values (vibrance, saturation, the mixer's
saturation bands) are now scaled together, tone values untouched and
negative ones — Vivid portrait's skin protection — left as written, until
the preset measures: Vivid and Vivid warm 1.30, Vivid landscape 1.38, Vivid,
strong 1.45, Vivid portrait 1.15, Punch 1.12. Measured as mean CIELAB chroma
over 30 raws from the library, as a ratio to the default rendering.
