In 1883, pioneering photographer Ukai Gyokusen buried several hundred of his glass negatives in a Tokyo cemetery – an act he considered as preservation. He died four years later, buried next to his photographs and with two tombstones detailing his life and career. With him went almost any evidence and recognition for his work. We speak to two photo historians about Ukai's career as well as looking at some exciting new discoveries made during the making of this episode.
