Saturation

The Saturation tool tones an image by changing the saturation and contrast of neighboring pixels. The tool works in two modes: in Saturate mode colors become more saturated, in Desaturate mode colors become less saturated. To quickly access this tool and switch between the Lighten, Darken, and Saturation tools press L.

The tool's parameters will be shown in a floating box over an image (by right-clicking the mouse) and also in the Settings Panel.

To change a parameter, enter a numerical value in the parameter's field and press Enter (Mac: Return) or adjust the slider.

• Size (1-1000). Size of the Saturation tool.
• Hardness (0-100). The softness of the tool's edge, where the effect is applied partially. At higher values the boundary between treated and untreated areas is more distinct; at lower values the transition between these areas is processed more smoothly.

• Strength (1-100). The strength of the effect. The higher the value, the stronger the change.

To change saturation in a straight line, pick a starting point by left-clicking the mouse, then, while pressing Shift, move the cursor to the desired end point and release Shift. If Shift is not released, then a new line will be drawn to each point where the mouse is clicked.
