Anotations

Scope note:

Refers to the practice of painting scenes while outdoors, rather than in a studio from sketches that may or may not have been made outdoors. It is often used to refer to impressionistic painting originating in France in the late 1860s that attempts to capture the transient effects of atmosphere and light by direct observation from nature.
