The Language of a Masterpiece: Light & Shadow

I’ve always believed that when a work of art moves you—whether toward awe or discomfort—it has already done something right. It’s made contact. It’s pulled you into a moment you didn’t live in before laying eyes on it. And that, to me, is enough to call it “good.”

The art world, however, is not built on feeling alone. Over time, it has developed its own language—a dense web of terms that don’t necessarily determine an artwork’s power, but do shape how we come to understand it. These are the words that place us a little closer to the artist’s decisions, that comment on their process, that point to what exactly has been achieved here and why that matters.

So today I want to kick off a new series on the terms you need to know as they pertain to light, space and scale, the grammar and narratives, and the techniques themselves.

These are the words that appear again and again in descriptions, essays and museum labels; Often left unexplained, as though we’ve all agreed, at some point, to already know them. But it’s difficult to love something we don’t understand, and even more so to understand something we were never taught.

So consider this a first step in the removal of that barrier. I hope that by the end of the series, you feel a little more equipped to name what you’re already sensing, a little more confident in your own responses.

That’s really all that matters: that the language meets your experience, not the other way around.

Here is the rest of this four-part series:

Not the kind you’re walking under in museum halls, but the kind an artist invents. It’s easy to assume it’s simply there—we can see the painting, after all. But it also shows us what the artist wants us to focus on, how our eyes are meant to move, what is made visible and what is withheld, all while establishing the mood through illumination alone.

From Italian chiaro (light) and scuro (dark), this term describes the use of strong contrasts between light and shadow to help build forms in three dimensions. It’s what allows a face to look like it’s coming out from a flat surface, what gives weight to a hand held out, depth to the fold of fabric. At its most dramatic, it feels almost theatrical, like a spotlight has been switched on in an otherwise dark room, and everything we’re meant to see steps forward into it.

This style is most prominently used in the Baroque Art movement that took place from the 1600s to the mid 1700s, and produced practitioners you might know, like Caravaggio and Artemisia Gentileschi from Italy:

(I’ve made a deep dive with these two artists’ work side by side in this video. Skip to 3:26)

Diego Velázquez and Francisco de Zurbarán from Spain:

and Rembrandt and Vermeer from the Netherlands:

(Both artists are discussed in a video I’ve made on the Art of Amsterdam. Skip to 2:14 for Rembrandt, and 14:29 for Vermeer)

Once chiaroscuro let shadow into painting, tenebrism made it a presence of its own. Derived from tenebroso, meaning “obscure” or “darkened,” it describes compositions where darkness fully dominates, and light appears in sharp, almost violent interruptions.

It’s most closely associated with Caravaggio, whose figures don’t so much sit in light as they are struck by it. The effect is meant to build tension. We might feel it in our chest: a sense that something important has happened, or is just about to.

Sfumato works in the opposite direction—not through creating intense contrasts, but through disappearance. The word comes from the Italian word sfumare, meaning “to evaporate,” and is related to fumo, or “smoke.”

Instead of outlining a form clearly, the artists practicing sfumato use shading to create a soft, almost imperceptible effect as the different colours melt into one another so gradually that the edges of different elements become impossible to pinpoint. It mimics the way our eyes see: when we focus on one thing, everything else blends softly into the background.

Leonardo da Vinci, who we know to be an avid student of human anatomy, began using this technique after his research into human vision.

We can see that in the soft transitions in the Mona Lisa. Our subject’s face doesn’t end so much as it dissolves into shadow. It’s the creation of an illusion through atmosphere, as we’re not necessarily looking at a boundary, as we are looking through it.

The technique was also adopted by the Italian artists Raphael and Giorgione, whose delicate tonal shifts make figures almost fuse with their surroundings, like they simultaneously belong both to themselves and the air around them.

Luminism is both a movement—emerging in the 1850s and lasting until the 1870s— and a painting style where the light itself is the focus of the painting, similar to what tenebrism is for shadows.

The word “luminism” means the painting of light, and it’s most often linked to 19th-century American landscape artists, the Hudson River School.

The brushwork often disappears entirely, polished so smoothly that the light can finally speak uninterrupted.

In British art, luminist qualities can be seen in James Abbott McNeill Whistler’s Nocturnes series.

It slips through clouds, touches water, and rests on skin in ways no artificial source could replicate. It tells us where to pause, where to linger, what to imagine beyond the edges of the canvas. Shadows can speak of secrecy or danger as light does of hope or a new day.

Following its path teaches us how painters see, how they feel, and how they think, and in doing so, it invites us inside the process as participants. Maybe that’s why it never feels ‘technical’ for me, because even when it’s meticulously constructed—and it often is—it still feels human, a guide we inherently know to trust.
