How to use the Blur tool

The Blur tool softens the picture only where you paint, for a busy background, a harsh edge or skin texture.

Where to find it

It is in the toolbar, in one slot with Sharpen and Smudge. Right-click the slot, or press and hold it, to choose between them. It has no shortcut key.

How to use it

1. Choose the tool. Right-click the drop icon in the toolbar and pick Blur. It has no shortcut key.
2. Set the brush. Choose Size and Hardness, and start with a low Strength.
3. Paint. Drag over the area to soften. Go over it again to blur more.

Options bar settings

• Size and Hardness: The brush diameter and how soft its edge is.
• Strength: How much each stroke blurs.
• Pressure: With a pen tablet, pressing harder makes the brush bigger.

Tips and common mistakes

• Hold Alt (Option on a Mac) to sharpen instead while you paint.
• To blur a whole background evenly, select the subject, invert the selection and use a blur filter; it is faster than painting.
