Brush in Photoshop is a powerful tool to paint something onto the layer, much like a paintbrush in real life. Photoshop comes with many brush templates in which you can adjust the size, intensity, and color quite easily. Even more, to expand creativity, it’s possible to create your own brush.
To create new brushes in Photoshop, all you in is, well, just Photoshop — no third-party apps required to perform this action. It’s recommended if you know the basic tools of the program.
Here’s how to create a new brush style in Photoshop CC (should be relevant on nearly all Photoshop versions).
1. Go to File > New.
2. Set the width and weight to be square because it’s better that way, then click Create.
3. Click Brush Tool (yes, we are using a brush to create a brush). Feel free to use Pencil Tool or other tools if you want to.
4. Now draw a brush style with it.
5. When you have done, click Edit > Define Brush Preset…
6. Set a name for the new brush and hit OK.
7. The new brush has been added and can be used.
Basically, what you need to do to create a new brush is just drawing something on the canvas and define it as a brush preset. You may even import a PNG picture and convert it into a brush preset with minimal effort.
