Harding says: "When I make these pictures, I track light over several days and make notes about its location at various times.I usually make drawings and smaller digital pictures to get a general idea of what I want. Light moves very fast so I have to be quick when making the final picture, which is hard with an 8x10. I make very long exposures and sometimes use steam or a fog machine to give the light a more discernable shape in the registered image."
