Every raw rendered through a camera profile — the library's DNGs with an
embedded profile, and CR2s given one — now renders differently: more
colourful in near-neutral tones. The profile's look table is no longer
applied unless its slider is raised; PROFILE_LOOK names the strength the
profile states.
Against the photographer's earlier exports with no look applied, the default
rendering scores the same with the look table at 100, 50 or 0 (held-out MSE
140, 140, 143), and is 9 % more colourful at 0: the table lowers the
saturation of near-neutral tones, which is exactly where the default
rendering was short of those exports. The user chose more colour.
