“At different times I've worked in different mediums. For me, the variation is not an artistic judgment, but a necessary choice. It's just as normal to eat with chopsticks, as it is to eat with forks or hands. Different circumstances call for different tools. I try to express ideas with the most appropriate available materials and forms. Very often the medium comes first, and then my reasons for it. Sometimes, I work with a medium I don't like out of curiosity. It is an experiment to challenge my pre-existing concepts and tastes. I've taken hundreds and thousands of photographs, and it's not because I like the medium. I wanted something to parallel my daily activities, and photography is the most logical way of doing that. I filmed documentaries because the medium reflects real conditions the most completely. I don't think artists should only work with what is handiest and most familiar, because the unfamiliar provides a challenge, and it creates another language. It defines the condition for new possibilities.”
