Create Your Own Brush in Photoshop Elements 10
After playing with all the various options Photoshop Elements 10 provides with the Brush tool, you might really like the Franken-brush you’ve created. There’s one additional way to create a brush. Elements allows you to create a brush from all or part of your image. The image can be a photograph or something you’ve painted or drawn.
Here's how to save the brush you've created through the Brush tool options:
Choose Save Brush from the panel menu on the Brush Preset Picker panel.
Name the brush.
Your new custom brush shows up at the bottom of the Brush Preset Picker drop-down panel.
Here’s how to create a brush from your image:
Select part of your image with any of the selection tools.
If you want to use the entire image or entire layer, deselect everything.
Choose Edit→Define Brush or Edit→Define Brush from Selection.
You see one command or the other, depending on what you do in Step 1.
Name the brush and click OK.
The new brush shows up at the bottom of your Brush Preset Picker drop-down panel. Note that your brush is only a grayscale version of your image. When you use the brush, it automatically applies the color you’ve selected as your foreground color.
