Chapter 14: Paint tools
Using paint tools
To specify paint tool options
The Brush tool, Clone Stamp tool, and Eraser tool are all paint tools. Each uses brushes to apply paint strokes to a
layer to add or remove pixels from the layer or modify the layer's transparency without modifying the layer source.
You can specify the properties of a paint stroke before you make it by choosing options from the Paint panel.
Note: Paint strokes appear as applications of the Paint effect. The Vector Paint effect behaves somewhat differently from
the Paint effect and uses a different set of tools. For more information, see "Vector Paint effect (Pro only)" on page 475.
You can apply the Brush tool and the Clone Stamp tool to the alpha channel (Alpha) of an image, the RGB channels
(RGB), or both (RGBA). When Alpha is selected, you can only add and remove opacity; swatches display colors in
monochromatic tones. Painting the alpha channel with 100% black has the same result as using the Eraser tool: It
creates transparent paint strokes. (See "About alpha channels and mattes" on page 242.)
Opacity and Flow settings can range from 0% to 100%. For the Brush tool, Opacity specifies the maximum amount
of paint coverage applied by the brush, whereas Flow specifies how quickly paint is applied. To simulate semi-trans-
parent paint, specify a low percentage value; to simulate opaque paint, specify a high value. For the Eraser tool,
Opacity specifies the maximum amount of paint and layer source removed by the brush, whereas Flow specifies how
quickly the removal occurs.
When a paint tool is selected, click the Toggle the Paint panels button
Tips panel.
