Paint and Chat: En Plein Air - A Little History of Painting Outside

En plein air—from the French meaning “in the open air”—refers to the practice of painting outdoors, directly in front of the landscape or subject. While artists had sketched from nature for centuries, en plein air painting became especially significant in the nineteenth century, when technological and cultural shifts made sustained outdoor painting possible. The invention of portable paint tubes in the 1840s freed artists from the studio, allowing them to travel with their materials and work quickly in changing light and weather.

The practice is most closely associated with the Impressionists, including Claude Monet, Camille Pissarro, and Pierre-Auguste Renoir. These artists sought to capture fleeting effects of light, atmosphere, and colour rather than idealised or carefully finished forms. Painting outdoors encouraged loose brushwork, visible strokes, and a brighter palette, as artists responded directly to what they saw rather than relying on academic conventions or preparatory drawings. Shadows were no longer rendered in brown or black but in blues, violets, and greens, reflecting optical observation rather than tradition.

En plein air also represented a philosophical shift. It aligned with modern ideas about immediacy, perception, and the lived experience of the present moment. Nature was no longer a backdrop for mythological or historical narratives but a subject worthy in itself. This approach challenged the hierarchy of genres upheld by academic institutions, elevating landscapes and scenes of everyday life.

Although closely linked to Impressionism, en plein air painting has endured well beyond it. From Post-Impressionists like Cézanne to contemporary painters, working outdoors continues to be valued as a way to sharpen observation, engage the senses, and maintain a direct, physical relationship with the world.
