How do art forgers operate?
<|assistant|>
Art forgers use sophisticated techniques to mimic the methods and materials of famous artists, using materials and brushstrokes indistinguishable from the originals. They often study techniques from reproduction painting books from the period, and will sometimes employ old master's techniques. They also sometimes work from a black-and-white photo as a reference in order to replicate authentic details from the original art work. Often, a forged painting could stand up to even close inspection, even though an expert would quickly recognize it as a fake.
