Some Examples from the Photo Corners & Hinges Brush Set:
These Brushes have all the preset options already set up so that you don't have to mess around trying to find decent option settings. But if you don't like the options I selected, you can change them to your heart's content. This makes them incredibly flexible for all your Photoshop painting needs.
