The Louisville Photo Biennial is in full swing with multiple venues featuring photography. As Paul Paletti is the festival director and co-founder, it’s important to pay attention to who he is showing in his eponymous gallery. This year it is Charles Traub, known for “his ironic, real-world, witness-color photographs.” The word tarradiddle (spelled differently) is British slang for pretentious nonsense. Through Traub’s lens, it’s a visual chuckle. If you like what you see, Traub put many of the photographs shown in the exhibition into the book “Taradiddle,” published in 2018. You may recognize one of his pieces as the cover of LEO’s Photo Biennial issue on Sept. 18. Check out leoweekly.com for a full schedule of Biennial events. —Jo Anne Triplett
