A., discusses his book, "Water is Key" during The Senior Arts Foundation's Arts & Community Forum 'Gil Garcetti: My Story, Act II' at the Main Library on Wednesday, January 21, 2009. (above)  Garcetti signs his book during the forum. Garcetti has always been an avid urban photographer. During his time as District Attorney he would carry a small camera with him at all times. After leaving the DA's office, Garcetti focused on art photography, initially producing two collections on the Walt Disney Concert Hall: Iron: Erecting the Walt Disney Concert Hall, focusing on the ironworkers who constructed the landmark, and Frozen Music, focusing on the finished building itself. Photos from these works were featured in an exhibit at the Smithsonian Institution's National Building Museum in Washington, D.C. and at the Pasadena Museum of California Art. His most recent exhibition, Dance in Cuba: Photographs by Gil Garcetti, was featured at the UCLA Fowler Museum of Cultural History in Spring 2006.
