At Creative Aging Arts Day Paul Ferrara curated an exhibit called Profiled.
The last project of the Life Maps class involved using silhouettes of the artists laid on top of their collages. The collages with colorful silhouettes on top were created without consideration of what the silhouette would look like on top. This creates a randomness that Paul Ferrara appreciates his students to embrace artistically. They are able to choose how to orient the silhouette on the artwork and consider the best visual layout. The black silhouette collages were planned deliberately with the use of the silhouettes in the process. You can tell that the artists thought about including facial features and details with the different paper scraps that they chose.
