The Smudge Brush Tool allows you to drag colour around an image, similar to dragging a brush or finger through wet paint. It can be used to blend colours and create interesting brush effects.
Settings
The following settings can be adjusted from the context toolbar:
Width—the brush (stroke) size in pixels. Type directly in the text box or drag the pop-up slider to set the value.
Flow—how fast the brush effect is applied (1% is very slow, 100% is immediate). Type directly in the text box or drag the pop-up slider to set the value.
Strength—defines the extent to the smudging. Type directly in the text box or drag the pop-up slider to set the value.
Force Pressure—Toggle to control brush size with pressure if using a pressure-sensitive device. This overrides brush defaults.
