If you can only get to one venue, though, the two shows at the Greenberg gallery make up a great combination. First, Gordon Parks: Centennial offers a broad overview of this extraordinary man and his career. Then Invisible Man zooms in on a single project, and we get a unique glimpse into Parks’ working methods. We see his love for Harlem, his feeling for its burdened residents. Somehow, he manages to make the invisible visible.
