Bredt predominantly uses female subjects that he places in exotic locations, interiors, and courtyard. He was fascinated with Oriental architecture; he built his house and studio in Ruhpolding, Germany in an Arabian style.
The work of Ferdinand Max Bredt was exhibited in Paris, Berlin, Chicago and London. Today he is little-known, but he was widely recognized in his lifetime for his works. Two of his paintings were chosen to represent his native Germany at the Worlds Columbian Exposition of 1893.
In addition to his regular paintings, he provided decorations and curtains for the new Karlsruhe Court Theater and the Dresden Semperoper. His decorations for the King Carl Hall at the Landesmuseum Württemberg pleased the King so much that he awarded Keller a title of nobility. Frederick I, Grand Duke of Baden, commissioned him to paint the History of Baden for the National Art Gallery. On a smaller scale, his etchings have been used to illustrate numerous books.
