Peeking Through the Paint: Mastering Depth with the Underpainting

There’s a secret trick to painting that can make a portrait leap off the canvas, giving it a depth that feels almost three-dimensional. It’s not about adding more layers of paint; it’s often about knowing exactly when—and where—to stop.

If you’ve ever spent hours on a figure drawing or a portrait study, you know the endless cycle of building up value and blending tones. We spend so much time worrying about the perfect topcoat, the flawless glaze, or the richest blend of acrylic. But sometimes, the most powerful artistic decision is the one you *don't* make.

In this week’s study, we are looking at a masterful portrait by Anthony Van Dyke, and the key lesson is strikingly simple: the eyes. The artist demonstrates how leaving the pupils and surrounding areas partially unpainted—a literal window to the underpainting—doesn't just reveal the layers beneath, it fundamentally changes the composition, giving the subject an intense, weathered realism.

This technique shows us how to use the raw canvas or the initial sketch layers not as mistakes, but as vital components of the final value structure. It’s a masterclass in utilizing negative space and allowing the initial sketch to contribute to the final depth and shadow.

The Magic of the Underpainting

When we talk about "underpainting," we are talking about the foundational layer of paint—the initial wash or sketch that establishes the basic value and tone. Usually, the goal is to cover that layer completely, but here, the artist deliberately maintains a contrast. By keeping the eyes exposed, the artist forces the viewer’s eye to perceive the depth and the underlying structure, making the gaze feel alive and immediate. It’s a powerful reminder that composition isn't just about what you put on the canvas; it’s about what you allow the viewer to see through.

This lesson applies across mediums. Whether you are working in soft charcoal on paper, blending delicate watercolor washes, or building up thick oils on an easel, remember to look for opportunities to use that underlying tone to your advantage. Don't feel pressured to completely obscure your preparatory sketches; let them inform your finished piece.

Getting Your Hands Dirty

The best way to learn this kind of subtle, observational technique is not through a Pinterest scroll, but through messy, focused practice. It requires time, a good sketchbook, and the company of other believers who understand the joy of getting paint under their fingernails.
