Abstract Long-Exposure Photographs of Colored Paper in a Cave
Los Angeles-based photographer Brice Bischoff has a project titled Bronson Caves. Between 2009 and 2010, Bischoff visited the caves in Los Angeles' Griffith Park with his 4x5 large format camera and some very large sheets of colored paper. He then used long exposure times to paint colorful blurs into the photographs by waving the papers around.
