Custom Brush Options

Photoshop provides many options to change the appearance of brushes, either to create new brushes or customize preset ones. Brushes can be completely altered, almost the point of being a new brush, simply by changing a few of their aspects. This help document provides in depth information on the different options available to you when customizing brushes in Photoshop CS3. For information on locating and accessing the Brush palette, refer to Using Preset Brushes.

return to topShape Dynamics

Changing the shape dynamics of your brush allows you to vary the size and rotation of each application of the brush within the stroke.
Brush stroke with and without shape dynamics
Brush Palette: Shape Dynamics Pane

Size Jitter
Adjusts the amount that each application of the brush can vary from the original size. Larger values cause more variation, and smaller values create more uniform sizes.

Control
Allows you to manipulate the size jitter in a variety of ways: see Control Options.

Minimum Diameter
Adjusts the smallest possible size that an application of the brush can be with consideration to size jitter. Specify a percentage of the original size.

Tilt Scale
This option is available only if the control is set to Pen Tilt and you choose to use a pressure-sensitive pen and stylus. It specifies how much the pen tilt affects your brush stroke.

Angle Jitter
Allows each application of the brush within a brush stroke to be rotated to a slightly different alignment. Larger values create more variation.

Roundness Jitter
Varies only the height of each instance of the brush.

Minimum Roundness
Minimum roundness of the brush tip when Roundness Jitter is enabled. Larger values create less jitter.

Flip X Jitter
Flips the direction of the jitter variation horizontally.

Flip Y Jitter
Flips the direction of the jitter variation vertically.

 

return to topScattering

Scattering allows you to set the distance off the cursor that you want individual instances of the brush tip to occur, as well as the number of instances you wish to see each time the brush is "set down" within the stroke.
HINT: To adjust the number of times the brush is "set down," change the spacing in the Brush Tip Shape section.
Brush stroke with and without scattering
Brushes Palette: Scattering Pane

Scatter
Distance that each individual application of the brush can deviate from the exact path of your brush stroke.
HINT: If Both Axes is selected, applications of the brush will stray both horizontally and vertically from your brush stroke; if unselected, applications will stray only vertically.

Count
Number of brush tips that are seen with each application of the brush within the stroke.

Count Jitter
Amount of variation in the number of brush strokes that are seen with each application of the brush within the stroke.

 

return to top Texture

Adding textures to brush strokes can add depth and distinction.
Brush Stroke with and without texture
Brushes Palette: Texture Pane

Texture
Allows you to select from a collection of texture patterns which can be applied to your brush stroke.
HINT: To reverse the areas of dark and light within the brush stroke, select Invert.

Scale
Determines the size that the texture pattern appears within the brush stroke.

Texture Each Tip
Begins the texture pattern over with each application of the brush rather than applying the pattern to the brush stroke as a whole.

Mode
Select a blending mode for the texture.

Depth
Applies a three-dimensional appearance to the brush stroke; light areas and dark areas within the original pattern appear as high and low points.
HINT: Low depth values minimize the appearance of texture, while high values highlight it.

Minimum Depth
Smallest possible percentage of the original depth that an application of the brush stroke can appear with depth jitter.

Depth Jitter
Amount of depth variation that can appear in your brush stroke.

 

return to topDual Brush

Dual Brush allows you to overlap the original brush stroke you created with a second, different stroke. The options available for the dual brush are the same as those for the original brush stroke, set in the Brush Tip Shape section. However, be sure to set a blending mode to define how the two strokes interact when they overlap.
Brushes Palette: Dual Brush Pane

return to topColor Dynamics

Color dynamics allow color variations to appear within your brush stroke.
NOTE: Color dynamics are not visible in your preview within the Brushes palette.
Brush Strokes with and without color dynamics
Brushes Palette: Color Dynamics Pane

Foreground/Background Jitter
Amount of fluctuation between the foreground and background colors that appear in your brush stroke.

Hue Jitter
Percentage that the color can vary within the brush stroke.

Saturation Jitter
Amount of fluctuation in the amount of gray that appears in the color of your brush stroke.

Brightness Jitter
Amount of variation that appears in the luminescence of your brush stroke.

Purity
Amount of gray that appears in your brush stroke's color.

 

return to top Other Dynamics

Brushes Palette: Other Dynamics pane

Opacity Jitter
Amount of variation in the transparency of the brush stroke.

Flow Jitter
Variation in the continuity of the brush stroke.

Noise
Makes the brush stroke grainier, especially at the edges.

Wet Edges
Causes the edges of the stroke to appear darkest, with the center slightly transparent.

Airbrush
Allows you to darken an area of color by hovering your mouse above it.

Smoothing
Steadies and smoothes minor variations within your brush stroke, such as those caused by a shaky hand.

Protect Texture
Applies the texture that you are currently using to all presets that have a texture specified.

 

return to topControl Options

When creating a brush stroke that includes any type of jitter, you have the option of selecting a control. Applying a control to a jitter allows you to control the amount of variation in your brush stroke. The type of control you select determines the method used to control the jitter. Each type of jitter offers different control options.

Control: Off
Jitter is applied randomly throughout the brush stroke.

Control: Fade
Causes the brush stroke to gradually disappear. Type a value in the text box at the right of the palette to specify how quickly the stroke disappears; larger numbers cause a slower disappearance.

Control: Pen Pressure
The jitter within your brush stroke varies according to the pressure of your pen; this option is relevant if you are using a pressure-sensitive pad and stylus in working with your image.

Control: Pen Tilt
The jitter of the brush stroke varies based on the tilt of your pen; this option is relevant if you are using a pressure-sensitive pad and stylus to work with your image.

Control: Stylus Wheel
The jitter of your brush stroke changes based on your adjustment of the stylus wheel; this option is relevant if you are using a pressure-sensitive tablet and a stylus with a fingerwheel to work with your image.

Control: Rotation
The jitter of your brush stroke varies based on the rotation of your pen; this option is available if you are using a pressure-sensitive pad and stylus to work with your image.

Control: Initial Direction
This option affects only angle jitter. The variation in rotation is based on the original orientation of each application of the brush and can only vary by the percentage selected in the Angle Jitter section.
EXAMPLE: If the angle jitter is set to 25%, and the control is set to initial direction, no instance of the brush can vary more than 90 degrees, or 25% of a circle, in either direction from its original orientation.

Control: Direction
This option affects only Angle Jitter. The variation in rotation is based on the original orientation of each instance of the brush stroke in relation to the path of the brush stroke. Each application can only vary from the original orientation by the percentage specified in the Angle Jitter section.

Excellence. Our Measure. Our Motto. Our Goal.
