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.

# Vivid: more colour than the default rendering (camera-profiles.md §9).
|
|
#
|
|
# These do the work themselves, and work on every photograph — a JPEG, a body with no profile. They lean on
|
|
# vibrance before saturation: vibrance lifts muted colours most and holds
|
|
# skin back, so a frame gets richer before anything in it looks painted.
|
|
# Saturation, which moves every colour alike, is used sparingly on top.
|
|
#
|
|
# Each changes only what it names (FR-DEV-6), so a corrected exposure or
|
|
# white balance survives applying one.
|
|
#
|
|
# How much colour each adds is measured, not guessed: mean CIELAB chroma on
|
|
# raws rendered with the default (DNG reference) rendering, as a ratio to that
|
|
# rendering. For scale, the photographer's earlier exports of the same kind of
|
|
# raws sit at 1.14 with no look applied and 1.27 with their everyday look.
|
|
# Vivid 1.30 and Vivid warm 1.30 sit just above that; Vivid landscape 1.38;
|
|
# Vivid, strong 1.45; Vivid portrait 1.15, with its skin bands held down as
|
|
# written. Tuned by scaling each preset's colour values together, never its
|
|
# tone ones.
