He worked in the Baroque period when the style of art was characterized by great drama, rich, deep color, and intense light and dark shadows. As opposed toRenaissance art, which usually showed the moment before an event took place, Baroque artists chose the most dramatic point, the moment when the action was occurring, This is not always the case with Velasquez who was a highly individual painter. Two styles of painting associated with Velazquez are "realism" and "Baroque." He also used a painting technique called "chiaroscuro
His realistic approach to the human figure, painted directly from life and dramatically spotlit against a dark background, shocked his contemporaries
