His work is defined by a technical approach to perspective and scale. In his depictions of the Interior of Saint Peter's during the 1700 Jubilee, Kraus captured the vastness of the basilica through meticulous linework. He combined architectural accuracy with small, narrative figures to provide a sense of human proportion. His friezes and ornamental designs demonstrate a mastery of Baroque symmetry. These prints were intended as art and reference materials for craftsmen.

Modern collectors value these prints for their clarity and historical detail. The monochrome nature of his copperplate engravings allows them to fit into contemporary interior schemes. Pieces such as his wooded landscapes or architectural studies offer a window into the aesthetic standards of the Holy Roman Empire. They provide a sense of order and structure to a room. His portraits, such as that of Henning Witte, remain examples of the formal style found in early eighteenth-century German printmaking.
