Photoshop CS6 Tutorial
How to Set Brush Scattering in Photoshop
Brushes are defined by one or multiple shapes in the brush tip. The Scattering options allow you disperse the shapes as you paint your document.
Open a new 1,024 pixel x 1,024 pixel document with a white background in Photoshop (File > New).
Click the Create a New Layer icon to add a new blank layer. You can experiment with your brushes on this layer.
Select the Brush tool and open the Brush palette by clicking the Brush palette icon or choosing Window > Brushes.
By default there should be several brushes already loaded in the palette.
Click the Brush Presets panel and choose Reset Brushes from the panel pull-down menu.
Select a brush. In this example we chose the Round Point Stiff brush from the Brush Presets panel. Click the Brush tab to return to the brush settings.
Click Brush Tip Shape at the top of the panel, then adjust the Spacing slider above the brush preview. As you adjust the Spacing slider, you see that the brush is just a series of dots. Adjust the slider so you can see the individual dots.
Click the Scattering tab to activate the Scattering feature.
Adjust the Scatter slider and notice how the dots are scattered over a wider pattern.
Count is used to add more density to the brush.
To vary the count as you paint, you can adjust the Count Jitter value.
Paint some lines in the document and notice how the settings affect the brush.
Saving Your New Brush
By starting with a preset brush, you can modify the settings, then choose New Brush Preset from the Brush palette pull-down menu. You can also save your brush by clicking the Create New Brush icon in the bottom of the Brushes panel.
Brushes Work With Many Tools
In addition to the Brush tool, the brushes also work with the Art History Brush, Blur, Burn, Clone Stamp, Dodge, Eraser, History Brush, Mixer Brush, Pattern Stamp tool, Pencil, Sharpen, Smudge and Sponge.
A limited round brush version is available with the Healing Brush tool and Spot Healing tool.
