Step-by-step: How to paint digitally with a natural media look
1 Color Dynamics are a good way of adding subtle hue variations that mimic the mixing of colours on a canvas. Foreground/background Jitter is great when you have a colour range in mind. Otherwise, Hue Jitter on a low percentage is usually fine.
2 Setting your brush’s Angle Jitter to Direction is a good way to create organic strokes that showcase your brush’s textures, such as the hairs on a bristle brush. I like to use this when painting hair or for bold impasto brush strokes that follow the form.
3 Manually adjusting the orientation of your brush can give you great control over the look of your brush strokes and is great for flat brushes. Using this method does require a little more patience, but it can yield organic and decisive painterly strokes.
