in the 19th century in france what gave impressionist painters so much new subject matter
Impressionism Prior to the Impressionists, other painters, notably such 17th-century Dutch painters as Jan Steen, had emphasized common subjects, but their methods of composition were traditional. They arranged their compositions so that the main subject commanded the viewer's attention. The Impressionists relaxed the boundary between subject and background so that the effect of an Impressionist painting often resembles a snapshot, a part of a larger reality captured as if by chance.[25] Photography was gaining popularity, and as cameras became more portable, photographs became more candid. Photography inspired Impressionists to represent momentary action, not only in the fleeting lights of a landscape, but in the day-to-day lives of people.[citation needed]
Renaissance art In Naples, the painter Antonello da Messina began using oil paints for portraits and religious paintings at a date that preceded other Italian painters, possibly about 1450. He carried this technique north and influenced the painters of Venice. One of the most significant painters of Northern Italy was Andrea Mantegna, who decorated the interior of a room, the Camera degli Sposi for his patron Ludovico Gonzaga, setting portraits of the family and court into an illusionistic architectural space.
