Part Three: Playing with Beetles
Sure, that’s pretty cool. But it gets cooler when you do some tweaks in the Brushes panel. First, we’ll undo the current beetles.
- Open the History panel (Window > History).
- Click on the New history state at the top of the History panel.
- Open the Brushes panel (Window > Brushes).
- Make sure that Brush Presets is highlighted in the top-left of the Brushes panel.
- Down in the bottom-right of the panel, change the Master Diameter to 100 px.
If you were to paint now, you’d get a cool, creepy effect. But we can do better than that.
- Back in the Brushes panel, click on the words Shape Dynamics on the left (if you just click on the check mark, you won’t see the options for it; you need to click on the words.)
- Slide the values for Size Jitter, Angle Jitter and Roundness Jitter all the way up to 100%. This gives you a variety of sizes, and flips and spins the beetle around. Watch the preview change as you move the sliders to the right.
- Click on the words for Scattering.
- Slide the value for Scatter to about 300%, and slide Count Jitter all the way up to 100%. This gives the painted beetles a more scattered effect.
- Finally, click on the words for Color Dynamics.
- Slide the value for Hue Jitter all the way up to 100%. This will result in a rainbow of beetles, although you won’t see this in the preview window of the Brushes panel.
- Now paint in the image window! Eek!
When you get to the end of Part One back there (before you define the brush), you want to end up with a black foreground image against a white background. The brush will be defined as the black parts.
If you wind up with the opposite – white on black – simply press Ctrl+I (Mac: Cmd+I) to invert the black and white.
