Frans Hals painted Malle Babbe in one sitting. There is no underdrawing. There are no separate stages. The brush went down onto a white ground, and the painting grew from there, wet paint into wet paint, with corrections made in mid-flight. You can see where hairs were scratched through the still-wet flesh paint of the collar, exposing the ground beneath. Hals did not wait for anything to dry. He did not plan in layers. He picked up his brush, looked at his subject, and painted until the canvas was finished. This is alla prima, and it is the most direct form of oil painting there is.
Alla prima, from the Italian for "at first attempt," is a painting method in which wet paint is applied directly onto previously laid wet layers without waiting for them to dry. The painting is typically completed in a single session. Unlike indirect methods that rely on underpainting, glazing, and multiple drying stages, alla prima minimizes intermediary phases. Compositional decisions and paint application happen simultaneously. The slow-drying properties of oil paint make this possible, allowing prolonged manipulation of the surface while everything remains wet.
This entry covers the history of alla prima, how it works technically, which artists defined it, and how to recognize it in a painting.
Alla prima is defined by its temporal constraint. The painter works wet-into-wet, meaning each stroke of paint is applied onto a surface that is still wet from previous strokes. This allows colors to blend on the canvas rather than on the palette, producing transitions that are smoother and more organic than anything achieved by mixing paint before application. It also means the painter must work quickly and decisively, because once the paint starts to set, manipulation becomes difficult.
The technique demands a synthesis of drawing, value, and color into a single act. In indirect painting, you can separate these concerns: draw first, establish values second, apply color third. In alla prima, you do all three at once. Every brushstroke must be the right color, the right value, in the right shape, in the right place. There is no opportunity to refine through layers. This is why Karel van Mander, the 16th-century painter and art theorist who taught Hals, wrote that alla prima was only suitable for experienced masters with a steady hand and an abundance of ideas.
A comparative study published in 2019 in the TOJDAC journal examined alla prima and plein air techniques through a qualitative framework. The research confirmed that alla prima is defined primarily as a material procedure structured around wet-in-wet manipulation of oil paint, governed by the temporal properties of the medium. The study found that alla prima minimizes intermediary phases, allowing compositional decision-making and paint application to occur simultaneously. Read the full study at TOJDAC.
Direct painting has existed since the inception of oil painting in the 15th century. Early Netherlandish painters like Jan van Eyck and Rogier van der Weyden primarily used indirect methods, but they occasionally employed alla prima passages for specific textures and details. During this era, direct painting was a specialized tool within a broader, highly controlled system.
The Baroque period marked the first significant move toward direct painting as a primary style. Diego Velazquez and Caravaggio explored the expressive potential of bravura brushwork, bold visible strokes that highlighted the artist's hand. But Frans Hals is the critical figure in the early history of alla prima. His portraits, characterized by their slashing brushstrokes and textural immediacy, were often dismissed as "sloppy" by traditionalists who valued the polished finish of painters like Vermeer. Hals recognized that the speed of alla prima could capture psychological vitality in a way that slow, methodical layering could not.
A 2024 study published by Amsterdam University Press examined the painting technique of Frans Hals's Malle Babbe in Berlin and New York, using infrared reflectography, macro X-ray fluorescence scanning, and hyperspectral imaging. The research confirmed that both paintings are done entirely wet-in-wet in the alla prima technique, described in Dutch as "ten eerste schier sonder teyckenen schilderen" (painting directly without preliminary design). An accidental scratch in the still-fresh paint of the collar in the Berlin version reveals that the picture was created directly on the preprimed canvas with no underdrawing.

The 19th century transformed alla prima from a specialized technique into the dominant method of Western painting. Edouard Manet used direct painting in controversial works like Le Dejeuner sur l'herbe (1863) to challenge the academic aesthetic of invisible brushwork. The Impressionists, led by Claude Monet, fully institutionalized alla prima as both a technique and a philosophical commitment to capturing the fleeting effects of light. Because atmospheric conditions change by the minute, the slow process of indirect painting was functionally incompatible with plein air work.
The spread of alla prima in the 19th century was facilitated by a technological innovation: the collapsible tin paint tube, patented by American painter John Goffe Rand in 1841. Before this invention, oil painting was an immobile, studio-bound craft. Paint had to be ground and mixed on site. The paint tube made it possible for artists to carry pre-mixed colors into the field, which made plein air alla prima painting practical for the first time.
Hals is the foundational figure in alla prima painting. The Laughing Cavalier (1624, Wallace Collection, London) and Malle Babbe (c. 1633, Gemäldegalerie, Berlin) are painted entirely wet-in-wet with no underdrawing. His brushwork is so direct that you can read the sequence of his strokes, seeing where he placed a highlight, adjusted a shadow, and scratched a correction into still-wet paint. Hals's alla prima produces a liveliness that slower methods cannot match.
Velazquez used alla prima passages in his late works, especially Las Meninas (1656, Museo del Prado, Madrid). The infanta's dress, the dog's fur, and the highlights on the figures are painted wet-in-wet with a directness that was centuries ahead of its time. Up close, these passages look like abstract smears of paint. Step back, and they resolve into precise descriptions of fabric, light, and form.
Manet served as the bridge between Old Master alla prima and modern direct painting. Le Dejeuner sur l'herbe (1863, Musee d'Orsay) and Olympia (1863, Musee d'Orsay) used alla prima to challenge the academic aesthetic of invisible brushwork. Critics called his brushwork "sloppy," but the directness was the point. Manet made the artist's hand visible in a way that Salon painting had suppressed for generations.
Monet made alla prima the defining technique of Impressionism. His series paintings, like the Haystacks (1890-1891) and the Rouen Cathedral (1892-1894), were painted in single sessions to capture specific light conditions. Each canvas records a particular moment of illumination, painted wet-in-wet before the light changed. The Impression, Sunrise (1872, Musee Marmottan Monet) that gave the movement its name is a classic alla prima painting, completed in one sitting.
Sargent brought alla prima into portraiture with spectacular results. Madame X (1884, Metropolitan Museum of Art, New York) and Carnation, Lily, Lily, Rose (1885-1886, Tate) are painted with a directness and confidence that makes each brushstroke feel inevitable. Sargent's alla prima combines the speed of Hals with the precision of academic painting, producing portraits that feel both spontaneous and authoritative.
Sorolla used alla prima to capture the atmospheric nuances of Spanish sunlight. The Siesta in the Garden (1904) and his beach scenes from Valencia are painted wet-in-wet with a facility that conveys the heat and glare of Mediterranean light. Sorolla's alla prima is more colorful and more physically energetic than Sargent's, reflecting his commitment to painting outdoors in direct sunlight.
Alla prima paintings have a freshness that indirect paintings lack. The brushwork is visible and confident. Colors blend on the canvas rather than in separate layers. You can often see where wet paint has been picked up and mixed with adjacent wet paint, creating transitions that are softer and less controlled than those in glazed paintings.
Look for visible brushstrokes that sit on the surface of the painting rather than being blended smooth. In Hals, the strokes are slashing and energetic. In Monet, they are smaller and more systematic, building up color through optical mixing. In Sargent, they are precise and economical, each one describing a specific form with a single touch. The common factor is that the strokes were laid down once and left alone. There is no evidence of reworking after the paint dried.
Alla prima is the opposite of indirect painting methods like glazing and underpainting, which rely on multiple drying stages. It often produces impasto because wet-on-wet application encourages loaded brushstrokes. The technique is closely associated with plein air painting, since working outdoors in changing conditions often necessitates wet-on-wet application.

Alla prima paintings are best appreciated in person because the physical quality of the brushwork is central to their effect. The Frans Hals Museum in Haarlem has the best collection of Hals's work, including Malle Babbe. The Museo del Prado in Madrid has Velazquez's Las Meninas. The Musee d'Orsay in Paris has Manet and Monet. The National Gallery in London has Sargent's Carnation, Lily, Lily, Rose. Comparing these across museums shows how the same basic technique produces radically different results depending on the painter's temperament and purpose.
