Beginning With Brushes
Get to know the Photoshop’s default brushes, then start adding your own
1 Brush options
Once you’ve selected the Brush icon from the toolbar, right-clicking anywhere on the canvas will bring up a small menu with shape and size options. Size is pretty straightforward, with a slider on the top right. Each of the strange shapes located in the white boxes below are alternate tip shapes, enabling you to create all kinds of different marks.
2 Alter your brush edges
Some tips, like the basic Round brush you start with, can also have the hardness of their edges adjusted. Accessing the slider labelled Hardness and moving it to the right will make for more distinct, hard-edged brush strokes, while moving it to the far left will create a soft airbrush effect.
3 Brush modes
When the Brush Tool is selected, there’ll be an options bar at the top of the screen with Mode and Opacity drop-downs menus. These both work the same way that their Layers window counterparts do, and the Mode settings are exactly the same for both (Lighten, Darken, Overlay and so on). Instead of controlling a whole layer, though, they’re just applying those settings to your individual brushstrokes.
4 Tip settings
The brush is the tool you’ll be using most often as an illustrator or concept artist, so take the time to get to know its features. Go to Window> Brush to open the Brush Window, where you’ll see a list of options such as Shape Dynamics (pressure on your drawing tool of choice dictates brush size), Dual Brush (use two brushes at once), Color Dynamics (use multiple colours at once) and Scattering (turns brush strokes into a scattering of marks in the shape of the brush tip).
5 Create your own brush
Photoshop comes with an impressive assortment of brush options, but when something more specific is needed you can create your own custom ones. Open a new document, and then draw your desired tip shape. Go to Edit>Define Brush Preset… from the top menu and it’ll add the new brush tip to your assortment, shaping it from the black and leaving transparent any white parts of the canvas.
6 Loading custom brushes
The internet is full of custom brushes available for download. I have some Nagel brushes that have served me well over the years. You’ll most likely be downloading the files in .Abr format, which you can then move to the Adobe Photoshop CS>Presets> Brushes folder on your hard drive. Open the Brush Preset window and click the drop-down menu option to bring up the Load Brushes option. Navigate to the file, double-click it and the new tip will appear in your menu.
