About brush options

You can simulate actual brush strokes by setting the rates at which the brush tool strokes fade out. You can specify which options dynamically change over the course of a brush stroke, including scattering, size, and color. The brush thumbnail in the options bar reflects the brush changes as you adjust the brush dynamics options.

You set brush dynamics options by selecting the brush tool and then selecting from the following controls from the More Options menu in the options bar.

Spacing
Controls the distance between the brush marks in a stroke. To change the spacing, type a number, or use the slider to enter a value that is a percentage of the brush diameter. (The brush thumbnail in the options bar dynamically changes to reflect your spacing adjustments.)
Increasing the spacing makes the brush skip.

Fade
Sets the number of steps until the paint flow fades to nothing. A low value makes the paint stroke fade away very quickly, while a value of zero has no fading effect. Each step is equal to one mark of the brush tip. Possible values range from 0 to 9999. For example, entering 10 for Fade produces a fade in 10 increments. For smaller brushes, you may want to set a value of 25 or larger. If strokes fade too quickly, increase the values.

Hue Jitter
Sets the rate at which the stroke color switches between the foreground and background colors. Higher values cause more frequent switches between the two colors than lower values. (To set the colors used by the color jitter option, see About foreground and background colors.)

Hardness
Controls the size of the brush’s hard center. Type a number, or use the slider to enter a value that’s a percentage of the brush diameter.

Scatter
Brush scattering determines how brush marks are distributed in a stroke. A low value produces a denser stroke with less paint scattering, and higher values increase the scattering area.

Angle
Specifies the angle by which an elliptical brush’s long axis is offset from horizontal. Type a value in degrees, or drag the arrowhead of the angle icon to mark the desired angle.

Roundness
Specifies the ratio between the brush’s short and long axes. Enter a percentage value, or drag a dot in the angle icon away from or toward the arrow. A value of 100% indicates a circular brush, a value of 0% indicates a linear brush, and intermediate values indicate elliptical brushes.
Adjusting roundness affects the shape of a brush tip.
