Brush Opacity

Last updated Mar 14, 2003.

As you are painting with the brush or pencil tools, you may not want to apply a fully opaque color. Photoshop allows you to modify the transparency of these tools so as you are laying down color with them, you can apply colors with varying degrees of opacity.

To modify the transparency of your brush or pencil tool, simply select the tool from the toolbox, and in the Options bar—as is shown in the following figure—drag the Opacity slider to adjust the painting/drawing opacity of your tool.

Once you've set the opacity of the tool you're working with, simply paint on the canvas to see those changes.
