Final answer:
In Berthe Morisot's 'Summer's Day,' impressionistic characteristics include the outdoor setting with natural light, the reflections of light in the water, and the depiction of contemporary subject matter, all of which are defining elements of the Impressionism movement.
Step-by-step explanation:
The impressionistic characteristics seen in Berthe Morisot's painting 'Summer's Day' are quite prominent and reflect the key aspects of the Impressionism movement. Outdoor setting with natural light: The painting showcases an open-air scene which is typical of the plein air approach adopted by impressionists to capture natural light and its transient effects. The light reflections in the water: Morisot's use of feathery strokes to portray the shimmering light on water and the reflections of the surroundings is a testament to the Impressionist technique of depicting light and its mutable qualities. The subject matter: Featuring women in an everyday setting reflects the Impressionist pursuit of modern life scenes over historical or mythological themes. Hence, all of these characteristics contribute to the overall impressionistic nature of the painting.
