plein-air (plān-âr´, Fr. plĕn-ĕr´) [Fr.,=open-air], term used for paintings or drawings made directly from nature and infused with a feeling of the open air. Painting outdoors is a relatively recent practice; the impressionists and the painters of the Barbizon school made plein-air painting an important dimension of their landscape work.
