Landscape Made Outdoors
Plein Air
En plein air is the act of painting outdoors, in direct or diffused light.
This method was practiced by some of my favorite artists: Paul Cézanne, Valentin Serov, Claude Monet, Konstantin Korovin, Alfred Sisley, Pierre-Auguste Renoir, Vasily Polenov, Isaac Levitan, and Igor Grabar.
