Activate the FX Brush tool and choose the Bristle Brush from the drop-down list.
The Bristle Brush produces a stroke consisting of multiple thin long parallel lines. The tool offers great creative opportunities and lets you draw everything that your imagination tells you.
Choose the brush color in the Color, Swatches, or Color Wheel panel, or from the image with the Eyedropper tool. To pick a color sample, press and hold the I key and then click the image with the Eyedropper tool. After the hotkey is released, the painting tool becomes active again.
The basic tool settings are shown in the Tool Options panel above the Image Window or by right-clicking on the image. To display the full list of parameters, press the tool icon in the Tool Options panel or use the F5 key. To specify the parameter settings, enter a numerical value in the parameter’s field or use the slider.
Size (10-400). The size of the base element of the brush (in pixels).
Line Width (1-100). The parameter defines the thickness of lines in a brush stroke. At low values, the lines are thinner and harder, increasing the value makes them wider and softer.
Density (1-100). The parameter sets the number of lines in a brush stroke.
Strength (10-70). The parameter defines the stroke brightness. At low values, the lines are more transparent, increasing the value makes them brighter and denser.
