joining me are john elderfield is the chiefsculpture at the human of modern art.eefs is the former chief curator of photography. i'm pleased to have them back at this table. welcome. when did this project begin. >> it began 20 years ago when a jenld of mine has been at jeff coons' skewed oh and he said this is no studio i've seen. it's like a workshop with lots of people there.leÑi and then it led to thinking well what is life over the years, where did this start what was the difference between a workshop and a studio. artists always wear tulles and then realizing as you just said the history is so broad, i mean going over centuries that you can't actually do it. >> i think the most prominent artist i ever went to a stood was lucien freud. one part of the studio was light and another part was totally dark and there he did different things. it was fascinating to see this place where so much creation keep out of. >> rose: you looked at photography and he's looking at paintings. is that the essential divide. >> absolutely. we worked together, we talked about the show
