How did painting directly from nature affect Pierre-Auguste Renoir’s work?

Painting directly from nature, or en plein air, was a transformative practice for Pierre-Auguste Renoir, encouraging a new freedom and experimentation in his style. By working in settings like the forest of Fontainebleau, Renoir and his peers moved away from the traditional studio-bound conventions of the time, focusing instead on capturing immediate visual impressions and the reality of modern life.1

This approach fundamentally shaped his Impressionist technique. By using small, multicolored strokes, Renoir successfully evoked the vibration of the atmosphere, the sparkling quality of foliage, and the luminosity of skin in outdoor light. His dedication to this method allowed him to create light-suffused paintings that emphasized vitality and the pleasures of life.1

However, Renoir’s relationship with nature-based painting evolved. While his early work was defined by these spontaneous, light-filled observations, he later experienced a crisis regarding the limitations of Impressionism. He eventually sought a balance, finding that while the sunlit landscapes of southern France encouraged his departure from strict Impressionist formulas, the spontaneity of nature also helped him recover an instinctive freshness in his art, which he later combined with a greater emphasis on form and volume.2
