Brushes are one of the fundamental features in Photoshop. With brushes, you can blend masks, create effects, add textures, and create lighting. There are thousands of brushes available online that you can download for your projects, but sometimes it can take hours to find the right brushes to get the specific look that you want. It can save you a lot of time if you just create your own brushes. You can use literally anything to create a custom brush. You just have to know how to convert your images or objects into the right format to define them as brushes.
