With its highly reflective floors, the Colvard Student Union Gallery is the perfect space to contemplate the conceptual works of the "Transparency-Reflections" photography show by David C. Lewis, architecture professor and associate dean of the College of Architecture, Art and Design. The artist urges viewers to take note of how the reflections and transparencies of the gallery interact with the parallel subject of the photographs. An opening reception will take place Thursday afternoon from 4-6 p.m.
