The standard brushes can emulate traditional media like charcoal, pencils, ink, or paint. But you don’t have to limit yourself to just the standard ones. It’s easy to make expressive, artful new brushes that don’t respond like anything conventional.
Fullscreen mode declutters the interface, leaving you with just your brush and your creativity. You can still reveal the tools you want, when you need them. This distraction-free approach means you can focus better on the art you make, not the tool you make it with.
