Healing With Pressure
If you're using a Wacom tablet and wireless pen with Photoshop, you've probably already uncovered the secret hiding place where Adobe tucked the pressure sensitivity controls. (Hint: They're in the Brushes palette.) But if you want to use pressure sensitivity with the Healing Brush, it's in a totally different spot. To turn it on, press Shift-J until you have the Healing Brush tool, then in the Options Bar, click directly on the Brush thumbnail, and a menu will pop up (it's not the standard Brush Picker). At the bottom of the menu, you'll see a Size pop-up menu, where you can choose Pen Pressure.
