Sfumato is the painting technique that creates a hazy, smoky effect by blending tones without sharp lines.
The word comes from the Italian sfumare, meaning “to evaporate” or “to fade like smoke.” Artists build the effect through extremely subtle transitions between light and dark, often layering thin glazes so that edges seem to dissolve. This can make skin, distant landscapes, and atmospheric backgrounds appear softer and more convincing.
Leonardo da Vinci is the technique’s most famous practitioner. It is strongly associated with the Mona Lisa, whose facial contours and enigmatic smile depend partly on delicate, almost imperceptible tonal changes. Leonardo also used sfumato in works such as The Virgin of the Rocks. Other Renaissance artists, including Raphael, Correggio, and Giorgione, employed related effects.
Sfumato is often confused with chiaroscuro. Chiaroscuro organizes a composition through strong contrasts between light and shadow, while sfumato softens the transitions between those tones. Impasto is different again: it uses thick, visibly raised paint.
