En plein air
also: Plein air painting · Open-air painting
En plein air - 'in the open air' - is the practice of painting finished or near-finished works outdoors, directly from the motif. Oil painters had long made outdoor sketches, but in the nineteenth century the practice became a program: technical advances such as the collapsible metal paint tube (patented in 1841) made it practical, the Barbizon painters worked from the forest, and the Impressionists put the outdoor study at the heart of their art. Working on site forces speed - light shifts within the hour - so the painter must commit color and value quickly. The results carry the freshness of first observation: visible strokes, bright unblended color and simplified forms that later generations came to see as modern painting's defining look.
Defining characteristics
- Painted from direct observation on site rather than from studio drawings
- Rapid, visible brushwork recording a short session of changing light
- Bright, often unblended color keyed to outdoor illumination
- Simplified forms and soft edges where light dissolves detail
- Portable kit: box easel, tube paints and compact supports
