Portrait of Katharine Elliot (died 1688), Dresser of Duchess Anne of York and First Woman of the Bedchamber of Queen Mary of Modena, the first and second Wives of James II of England, respectively

The portrait features a stark contrast between the subject's pale face and the dark surroundings, achieved through the use of deep shadows. This chiaroscuro technique emphasizes the subject's facial features, creating a sense of drama and focus.

As a court painter to several English monarchs, John Riley's work reflects the conventions of late 17th-century portraiture, including the use of chiaroscuro to add depth and emphasis to the subject.
