New Yorker Kurt Novak says his \"Detroit Portraits,\" at Revolution Gallery in Ferndale, celebrates the creative spirit in his old hometown. The exhibit also celebrates the artist\'s skill at turning a challenging way of making art into expressive medium all his own. Novak was an art student at Wayne State University during the late 1970s. The artist scanned painter Robert Wilbert, WSU professor emeritus, with still-life objects that appear in his canvases.
