In conjunction with the exhibition The Sun Placed in the Abyss at the Columbus Museum of Art, Beeler Gallery presents a talk by the New York-based artist Lisa Oppenheim. Oppenheim's experimental imagery often starts with online source material, which she then processes with techniques old and new. Nature is a frequent subject, but the end image has been distilled through so many methods that the viewer is prompted to ask, What am I really looking at? Oppenheim will talk at 6:30 p.m. Wednesday, Oct. 26, at the Canzani Center Auditorium at Columbus College of Art & Design (60 Cleveland Ave.). The event is part of the Beeler Gallery Visiting Artists & Scholars Series and is free and open to the public. For more information, visit beelergallery.org.
