Napoleon III style
The Napoleon III style was a highly eclectic style of architecture and decorative arts, which used elements of many different historical styles,and also made innovative use of modern materials, such as iron frameworks and glass skylights. It flourished during the reign of Emperor Napoleon III in France (1852–1871) and had an important influence on architecture and decoration in the rest of Europe and the United States. Major examples of the style include the Opéra Garnier in Paris by Charles Garnier (1862–71), the Bibliothèque nationale de France. and the Church of Saint Augustine (1860–1871). The architectural style was closely connected with Haussmann's renovation of Paris carried out during the Second Empire; the new buildings, such as the opera, were intended as the focal points of the new boulevards.
Impressionism
In the middle of the 19th century—a time of change, as Emperor Napoleon III rebuilt Paris and waged war—the Académie des Beaux-Arts dominated French art. The Académie was the preserver of traditional French painting standards of content and style. Historical subjects, religious themes, and portraits were valued; landscape and still life were not. The Académie preferred carefully finished images that looked realistic when examined closely. Paintings in this style were made up of precise brush strokes carefully blended to hide the artist's hand in the work. Colour was restrained and often toned down further by the application of a golden varnish.
