3. Instant Starry Sky
This technique is very useful when you need to add fine details to complex illustrations.
It doesn't replace a real starry sky but, if used with attention, can produce convincing results.
Step 2 : Select the Brush Tool (B) then hit F5 to bring up the Brushes palette.
Adjust Diameter and set a large Spacing. Use the preview at the bottom for reference. Now instead of painting solid strokes you will dot the sky with stars. (See Palette)
Set Shape Dynamics. Increase Size Jitter to vary the diameter of the stars. For Control choose Off if you don't have a tablet. Then start saving to buy one. (See Shape Dynamics)
Set Scattering. You want your stars to pop up at random spots so use the preview as guide. (Scattering)
Set Opacity Jitter. This is crucial in making some stars appear closer and others appear farther. If you have a tablet you can control opacity and size by varying the pressure, thus having more control. If you don't have a tablet it's ok. (Jitter)
Some stars are small and bright, others are big and close to us but duller. Randomness looks good here.
Step 3 : Now you can have fun painting the galaxy away!
