Which of the following would probably be the most effective choice for a speech topic?

A strong speech topic is focused enough to cover clearly in the time available. “The contributions of Janusz Kaminski to modern cinema” centers on one filmmaker and his work, while “the art of filmmaking” and “directing & producing films” are very broad. “Cinematography & lighting design in film” also covers a wide subject, so B is the most focused choice.
