Tone

Recover highlights or open shadows by tone zone, keeping colours natural.

Parameters

Parameter	What it does
Highlights	Negative recovers bright areas (up to −2 stops), positive brightens them.
Shadows	Positive opens dark areas (up to +2 stops), negative deepens them.

Local contrast: Clarity for large-scale midtone contrast, Structure for fine detail.

Parameters

Parameter	What it does
Clarity	Large-scale local contrast in the midtones: adds punch or softens.
Structure	Fine-detail local contrast: crisper texture without large halos.

Good to know

• Natural limits halos, Punch adds saturation, Neutral leaves colour alone, Classic is the strongest.

The film-like tone curve from scene light to display: contrast around a pivot, toe and shoulder.

Parameters

Parameter	What it does
Contrast	Slope of the tone curve around the pivot: more contrast spreads midtones apart.
Pivot	The scene level that stays fixed when contrast changes (0.18 = middle grey).
Toe	Softens and lifts the deepest shadows, like the toe of a film curve.
Shoulder	Rolls highlights off smoothly instead of clipping them, like the shoulder of a film curve.

Black point, white point and midtone for RGB or each channel, with output limits and eyedroppers.

Good to know

• RGB, Red, Green and Blue tabs; top handles set output, bottom handles input black, midtone and white.
• Eyedroppers: in the RGB tab they set each channel's point, removing a cast.

Point curves for RGB and each channel on the display-encoded image.

Good to know

• Click to add a point, drag to move, double-click or drag out to remove.
