Some artists hope to show viewers beauty. Others aim to explore erosion and decay. “Exile,” a multidisciplinary one-night exhibit, seeks to showcase the frayed edges of our society. On display will be a massive photographic work by David Salinas that features a man named Ed whom Salinas saw collecting cans outside his studio. The incredible work is done without computer manipulation, instead utilizing the messy and grueling process of applying chemicals with a paint roller to bring out the picture. “I HATE rules,” said Salinas by e-mail. “In my darkroom, anything goes.” Other artists include Ronny Quevedo, Blanka Amezkua, Darwin Arevalo, Caroline Chandler and Oscar Rene Cornejo.
