pressure, pen tilt, position of the pen thumbwheel, or rotation of the pen.
Initial Direction Bases the angle of brush marks on the initial direction of the brush stroke.
Direction Bases the angle of brush marks on the direction of the brush stroke.
Roundness Jitter and Control
enter a percentage indicating the ratio between the brush's short and long axes. To specify how you want to control the roundness variance of
brush marks, choose an option from the Control pop-up menu:
Off Specifies no control over the roundness variance of brush marks.
Fade Fades the roundness of brush marks between 100% and the Minimum Roundness value in the specified number of steps.
Pen Pressure, Pen Tilt, Stylus Wheel, Rotation
value based on the pen pressure, pen tilt, position of the pen thumbwheel, or rotation of the pen.
Minimum Roundness Specifies the minimum roundness for brush marks when Roundness Jitter or Roundness Control is enabled. Enter a
percentage indicating the ratio between the brush's short and long axes.
Brush Projection (CS6) Specifies that as you paint with a stylus, changes to tilt and rotation alter the tip shape.

Color dynamics brush options

Color dynamics determine how the color of paint changes over the course of a stroke.
Brush strokes without color dynamics (left) and with color dynamics (right)
Apply per tip Specifies changing color for each distinct tip stamp in a stroke.
If unchecked, dynamic changes occur once at the beginning of each stroke. You can vary color between strokes, rather than within each individual
stroke.
Foreground/Background Jitter and Control
To specify a percentage by which the color of the paint can vary, type a number, or use the slider to enter a value. To specify how you want to
control the color variance of brush marks, choose an option from the Control pop-up menu:
Off Specifies no control over the color variance of brush marks.
Fade Varies the color of paint between the foreground color and the background color in the specified number of steps.
Pen Pressure, Pen Tilt, Stylus Wheel, Rotation
on the pen pressure, pen tilt, position of the pen thumbwheel, or rotation of the pen.
Hue Jitter Specifies a percentage by which the hue of the paint can vary in a stroke. Type a number, or use the slider to enter a value. A lower
value changes the hue while maintaining a close proximity to the hue of the foreground color. A higher value increases the difference between
hues.
Saturation Jitter Specifies a percentage by which the saturation of the paint can vary in a stroke. Type a number, or use the slider to enter a
value. A lower value changes the saturation while maintaining a close proximity to the saturation of the foreground color. A higher value increases
the difference between saturation levels.
Brightness Jitter Specifies a percentage by which the brightness of the paint can vary in a stroke. Type a number, or use the slider to enter a
value. A lower value changes the brightness while maintaining a close proximity to the brightness of the foreground color. A higher value increases
the difference between brightness levels.
Purity Increases or decreases the saturation of the color. Type a number, or use the slider to enter a percentage between –100 and 100. At –
100%, the color is fully desaturated; at 100%, the color is fully saturated.

Transfer brush options

Transfer brush options determine how paint changes over the course of a stroke.
Specifies how the roundness of brush marks varies in a stroke. To specify the maximum percentage of jittering,
Varies the roundness of brush marks between 100% and the Minimum Roundness
Specifies how paint varies between the foreground color and background color.
Varies the color of paint between the foreground color and the background color based
