In s3e53 of Platemark, hosts Ann Shafer and Tru Ludwig conclude their conversation with Carol Wax, artist and author of The Mezzotint: History and Technique. In this second half, we talk about how all copper plates are not created equal, the intricacies of inking a mezzotint plate, the number of black inks used by John Martin (aka Apocalypse Martin) to effect the glorious lights and shadows in his mezzotints, J.M.W. Turner and his Liber Studiorum. The effect Phjilip Pearlstein had on her artistic thinking, her devotion to her dogs, and her great admiration for the facility of Fred Mershimer.
