Another exhibition of photography to consider is "Terra Incognita: Photographs of America's Third Coast" at the Polk Museum of Art, 800 E Palmetto St., Lakeland. Richard Sexton created a portfolio of the Gulf Coast over a 15-year period. In the 57 photographs on view, we see marshes, scrubland, forests, beaches and swamps in black and white, which contributes to their visual lyricism. It continues through Sept. 13. Hours are 10 a.m. to 5 p.m. Tuesday through Saturday. Admission is $5 adults, $4 seniors and free for children and students with ID. polkmuseumofart.org or (863) 688-7743.
