The Art of the Underpainting: Building Depth in Your Landscape Paintings

There’s a specific kind of magic that happens when you look at a truly successful landscape painting—that deep, atmospheric sense of space and life. It’s not just about the pretty colors you slap on the canvas; it’s about the layers, the subtle shifts in value, and the careful way a professional builds depth from the ground up. For us Rogue Artists, who find solace in the scent of turpentine and the scrape of charcoal on paper, mastering these foundational techniques can be the difference between a nice sketch and a stunning, immersive piece.

Today, we're diving into the world of underpainting—the crucial, often invisible work that gives a landscape its bones and its drama. It’s all about knowing where the shadows live, how to make the light pop, and how to build contrast without making your painting look overly theatrical.

Building Depth, One Shadow at a Time

Whether you're working with oils, acrylics, or even rich gouache, the principles of composition and value remain constant. When tackling a large scene, like a winter shed nestled among trees, the trick is to work in sections, focusing on the underlying structure first. The artist in our source video demonstrates a beautiful process of starting with foundational washes and atmospheric color to establish the overall mood and tone.

Notice how the artist first uses soft, blended washes—like mixing a soft bluish color with a touch of Umber—to create the sky and background trees. This isn't the final sky color; it's the *suggestion* of the sky. This initial layer establishes the overall value and color harmony, allowing the subsequent details to sit correctly within the picture plane.

The little things make the difference. It’s not till you get back that you’ll see them. It’s the little things that make a difference and the overall painting really makes a difference.

This philosophy applies everywhere—from the distant background trees, which are barely visible until you step back, to the subtle cracks in an old wooden shed. The underpainting isn't meant to be seen; it's meant to be felt. It is the foundational shadow, the first wash of brown and purple applied to the barn's dark side. By establishing these deep, cool tones first, the eventual highlights you add on top will appear brighter, crisper, and more convincing.

The Importance of Contrast and Perspective

A key lesson here is that contrast doesn't have to be a brutal, jarring opposition. The artist notes that they want “little pockets of contrast.” This means thinking about the relationship between the light source and the objects. If your light is coming from the upper left, the door, the side of the barn, and the ground will naturally fall into shadow. By underpainting those dark areas first, you create a visual 'anchor' that makes the eventual highlights feel earned.

And let’s talk perspective. While the artist admits that sometimes they do it by feel, the suggestion to draw out the basic structure—whether on paper or directly on the canvas—is invaluable. Remember that perspective is your blueprint. Once you have that structure in place, your brush can follow, even if the details feel a little messy. It's the playful, tactile process that makes painting so rewarding.

Making the Details Pop

The final act of painting is always about the details. After the main washes are dry, the artist carefully works on the door and the gaps between the boards. By adding a very dark, rich color (a mix of brown, black, and purple), they create a dramatic sense of depth, making the open door look genuinely three-dimensional. This is the power of value—the difference between the darkest shadow and the lightest highlight—that breathes life into a still life, a landscape, or a portrait.

If you’re feeling inspired to tackle a large piece, remember that you don't have to master everything at once. Start by sketching out a simple composition, then treat your canvas like a series of mood boards, building layers of color and value until the entire scene finally comes alive. Don't worry about getting it perfect; just keep getting your brush in the paint.
