From the Italian word for ???smoke???, a technique of painting in thin glazes to achieve a hazy, cloudy atmosphere, often to represent objects or landscape meant to be perceived as distant from the picture plane.<br><br>Italian for "shaded off". Gradual, almost imperceptible transitions of color from light to dark.<br><br> Italian term meaning smoke, describing a very delicate gradation of light and shade in the modeling of figures; often ascribed to da Vinci's work (also called blending). Da Vinci wrote that 'light and shade should blend without lines or borders, in the manner of smoke', in his Notes on Painting.<br><br>In painting, the technique of blurring or softening sharp outlines by subtle and gradual blending (feathering) of one tone into another. The smokelike haziness of this effect slightly lessens the perception that a still image is entirely still, instead lending a vague sense of movement. It is best known in the paintings of the Italian Renaissance artists Leonardo da Vinci (1452-1519) and Correggio (Antonio Allegri) (Italian, 1489-1534).
