CALLICOON CENTER, NY — The Jeffersonville Branch of the Western Sullivan Public Library, 19 Center St., is showing photographs of mountains in Alaska by J. Kreznar through mid June. Krezner is an artist living in Callicoon Center whose usual medium is painting, but who has expanded to photography over the last three years. Kreznar said, “I chose black and white because it is closer to capturing the essence of the landscape. I wanted the mountains to look big.”
