The Art Gallery of Ontario has brought in an art exhibition that some visitors have described as "thrilling" and "inspirational." It's the work of British painter Joseph Mallord William Turner. The exhibition is called "J.M.W. Turner: Painting Set Free" and focuses on the artist's late work, made after the age of 60. It comes to Toronto after having been shown at the J. Paul Getty Museum in Los Angeles and the Fine Arts Museums of San Francisco.
