To complement the Harry Callahan and His Students: A Study in Influence exhibition, Gallery 400 presents an evening's discussion, featuring participants Joe Jachna, Kenneth Josephson, and other Illinois artists trained at the Institute of Design by Callahan. Peter Hales, a photographer and historian of photography, will speak on how an Institute of Design training fits into trends in twentieth-century photography education. Joe Jachna and Kenneth Josephson, well-known area photographers, are featured in the exhibition. Jachna and Josephson will be joined by other Callahan and ID-trained Illinois photographers not in the exhibition to reflect on Callahan, their own education and work, and photo education generally. This latter group will most likely include Art Sinsabaugh and Charles Swedlund, who, like their teacher, both photograph and teach photography, and Joe Sterling, who has made his way outside of academia.
