Image from the “Shadows and Light’’ show at The Franklin Gallery at Riverstones Custom Framing, in the very lively and interesting city of Rochester, N.H., through January. The show, coordinated by Peter Abate and featuring 34 artists, is a traveling exhibition. “Shadows and Light’’ is about the interplay and interpretation of shadow and light in art. The pieces in “Shadows and Light’’ explore the technical aspects of light and shadow as well as the symbolic and metaphorical ways these elements are expressed.
