How do art forgers operate?
<|assistant|>
Art forgers typically use techniques such as re-touching, manipulation, reconstruction and misattribution to alter the existing art or create a forgery. They may employ a combination of modern and traditional techniques including using paints, varnishes and special filters to alter the colors of a painting, replicating patinas to imitate the age of a work and retooling the surface of a sculpture. They may also employ sophisticated forensic analysis, including DNA testing, to create a compelling and persuasive fake art.
