En plein air is a French expression which means "in the open air", and is used to describe painting outdoors. (also called peinture sur le motif -- "painting on the ground"). In the 1870s, painting outdoors increased with the introduction of paints in tubes, followed by the invention of the portable "box easel". The popularity of painting outside has endured over the years ~ especially throughout the summery golden vistas of California... my very favorite landscape.
