What is the history of plein air painting?
Some art historians attribute the 18th century painter Alexandre-Francois Desportes the honor of the first plein air painter. Plein air became popular with the Barbizon School (circa 1835-1870 with artists like Rousseau, Corot, and Millet) and the Impressionist movement (circa 1870 with artists like Monet, Renior, Pissaro, Cezanne, Degas, and Van Gogh).
