Brush Noise and Wet Edges
Photoshop CS6 Tutorial
How to Add Brush Noise and Wet Edges in Photoshop
The brush Noise option is similar to the Dissolve blending mode. The brush edges of a soft brush become speckled with the addition of noise.
To make your paint look like a watercolor brush, you can activate the Wet Edges option. With Wet Edges, the edges become loaded with slightly more pigment.
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 the new brushes on this layer.
Select the Brush tool and open the Brush palette by clicking the Brush palette icon or choosing Window > Brushes.
Click the Brush Presets tab and select a soft edge round brush, then click the Brush tab to return to the brush settings.
Draw a line in the workspace using the brushes default settings.
Click the Noise checkbox and draw a second line. Notice the how the stroke's edges now appeared speckled.
Deselect the Noise checkbox and click to select the Wet Edges option. Draw a line in the workspace. The new brush paints darker edges very similar to a watercolor brush.
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.
