Art Saint Louis challenged artists to capture the golden hour — that magic time at dawn and dusk when sunlight gives the world a luminous beauty — in the medium of their choice for the gallery's new show. The works selected for the juried exhibit run the gamut. Lorraine Cange photographed a Jewel Box lily pond in black and white, focusing on the pattern of shadows formed on the lily pads. Russell Vanecek captured the glory of a Flad Avenue alley bisected by a bright box of brilliant sunlight. Bob Rickert's abstract photograph of the Palouse hills in Washington State is a model of contrasts, with stark shadows giving way to glowing hilltops. The Golden Hour is at Art Saint Louis (1223 Pine Street; www.artsaintlouis.org). The show continues through October 27, and the gallery is open 7 a.m. to 5 p.m. Monday through Friday and 8:30 a.m. to 4 p.m. Saturday. There will be a rescheduled closing reception from 5-7 p.m. Saturday, October 21.
