Were not going to go into too much detail with the eraser tool, simply because you should already have a pretty

good understanding of how it works. How so?

Well, like many other tools in Photoshop, the Eraser Tool uses brushes which effect the size, shape, and

hardness of the tool. Essentially, the eraser tool is controlled in the exact same way as the brush tool, only it

erases rather than paints.

In order to use the brush tool to its full extent, its important to understand what exactly a brush is in Adobe

Photoshop. A brush uses brush presets that are predefined (or user defined). A brush preset is any brush tip

with defined characteristics (such as size and shape).

Think of brushes in Photoshop as a large collection of different

paintbrushes, each with a different shaped tip. Imagine when you press the tip of one of these paintbrushes

against a canvas, the shape of the tip is imprinted immediately. Its a rough explanation, but it gets the basic

idea across.

Brushes in Photoshop have plenty of other characteristics which make them entirely unlike a real world paint

brush. By manipulating these attributes, we can create entirely new brushes that act in unique ways. You could

create a brush that changes in shape and size as you are painting, a brush that scatters itself in random

directions, and even a brush that becomes more and less transparent while creating strokes. The possibilities

are literally endless.

Lets Create a Quick Brush for demonstration purposes.

Create a new document, 200px by 200px with a white background. Select the Brush tool, and in the options bar

select the first brush preset from thebrush preset picker (activated by clicking on the small down arrow next to

the current brush).

In the Brush Tip Shape area, set the diameter of your brush to 20px. By changing the diameter, you affect the

size of the brush.

Now go to Shape Dynamics and set thesize jitter option to 100%. By changing shape dynamics, youre adjusting

how a brush mark changes during a stroke.

Finally, go to Scattering, and setscatter to 300% with a count of 1. Scattering will affect placement and number

of brush marks.

Try painting with your brush now, and you ought to see a huge difference from when you first started!

Modifying brushes is really that simple!
