Paint Brushes
From the anatomy of animal hair to the physics of fluid dynamics on digital canvas. A guide to the most essential instrument in an artist's arsenal.
Beginner: Anatomy & Shapes
Every brush is composed of three parts: the handle (wood or plastic), the ferrule (the metal band holding everything together), and the bristles (natural hair or synthetic filaments). The shape of the bristles dictates the exact footprint of paint left on the canvas.
The Round Brush
A versatile classic. The pointed tip allows for fine detail work and sweeping, variable-width wash strokes when pressed down. The belly holds a lot of water.
Intermediate: Pressure & Opacity
Unlike a digital pen tool, a physical brush is highly responsive to the artist's kinetic energy. The amount of Pressure applied against the canvas alters the stroke's width, while the Paint Load (how wet the brush is) dictates the opacity and texture.
Increased downward pressure forces the bristles to splay outward, yielding a vastly thicker stroke. Light pressure creates delicate, hair-thin lines.
A fully loaded wet brush creates an opaque, contiguous line (Impasto). A brush with very little paint catches only the high points of the canvas texture, creating a scratchy, broken effect known as "Dry Brush."
Advanced: Specialty Brushes & Techniques
Beyond the foundational three shapes, a painter's toolkit expands into specialized brushes engineered for specific tasks — from laying vast washes to rendering a single strand of hair. Mastery of these, combined with technique, separates a competent painter from a deliberate one.

How to Use
Lightly drag across the canvas to split the bristles into individual strands. Use with a dry brush for soft blending without hard edges between tones.
Painting Technique Reference
The brush is only the instrument — technique is the language. These are the six foundational mark-making methods every painter builds a vocabulary from.
Impasto
MEDIUM: Oil, Heavy Acrylic
Paint applied so thickly it creates 3D texture on the canvas. The palette knife or stiff hog-hair brush leave physical ridges that catch light. Favored by Van Gogh and Rembrandt.
Glazing
MEDIUM: Oil, Acrylic
Thin, transparent layers of color laid over a completely dry base. Each glaze modifies the color beneath without mixing with it, creating luminous depth impossible with a single opaque layer.
Scumbling
MEDIUM: Oil, Acrylic, Pastel
A dry, rough brush loaded with opaque paint is dragged lightly across a dry layer below, allowing the lower color to show through the gaps. Creates atmospheric haze, weathered textures, and broken light.
Wet-on-Wet
MEDIUM: Oil, Watercolor
Fresh paint is applied directly into wet paint. Colors blend softly on the canvas surface. The technique demands speed and confidence, as there is no rework once the brush touches wet pigment.
Dry Brush
MEDIUM: All
A brush with very little paint, worked across a textured surface. Only the raised peaks of the canvas catch pigment, leaving a broken, scratchy stroke that is perfect for wood grain, fur, and sparkling water.
Feathering
MEDIUM: Oil, Acrylic
Soft, whisking strokes made with the very tip of the bristles to blend two adjacent color zones together. The brush barely grazes the surface, pulling color across the boundary with each light pass.
