Brush Hardness, Size, and Opacity
- Brush Hardness: Always 100%.
- Spacing: Keep under 30%.
- Brush Size: The smaller the size, the cleaner the sketch. I like 5-10 pixels.
- Shape Dynamics: Set Size Control to Pen Pressure (for tapered ends).
- Transfer: Set Opacity Control to Pen Pressure.
These settings will help you create line art like the examples below. The key to clean line art is to take your time making fluid, deliberate strokes. You don't always need the Shape Dynamics option on, but if you want to make your sketches look more traditional, then it definitely helps.
Base Colors and Blocking Out Tones
- Brush Hardness: Varies on the effect. Soft brushes create realistic shadows while hard brushes help to sculpt. I generally stick to 30-50%.
- Brush Size: Bigger is better for fast application.
- Shape Dynamics: Remember to turn the Pen Pressure Off after sketching, or the brush strokes will be tapered and hard to apply.
No matter how harsh this initial step may be, the blending phase will help to smooth any details out.
Blending
Whether you're painting skin or a beautiful sky, eventually soft brushes come into play. And the harder the brush, the harder it is to blend. Start with the lowest setting for Hardness in order to gauge whether or not you need to increase it. The style you're going for will make this step purely subjective, so experiment to see what works best.
- Brush Hardness: Start with 0% and increase according to your needs.
- Brush Size: Large brushes cover more area so you'll rarely need to use tiny brushes.
- Shape Dynamics: Pen Pressure should still be off during this phase.
Detailing
Digital Paintings are best painted at high resolutions. But the bigger they get, the harder it is to paint details because the file size becomes massive. Try to combat brush lag so that you can paint in those details for the best quality painting.
- Brush Hardness: Maintain between 60-100% for crisp details.
- Brush Size: Depends on your painting resolution. Generally speaking, use smaller brushes to help you get into the nooks and crannies of your paintings for better details.
Specialty and Texture Brushes
Everyone loves brush packs. Why draw a bunch of leaves or fur by hand if I have a brush that can do it for me?
The main reasons why you would choose texture and specialty brushes is to either create a certain effect, add texture of course, or simply convenience. You can save a lot of energy and time by using a brush that creates an effect in a matter of seconds.
