Still on my Hockney trip. i have just caught up with the Andrew Marr interview with H and tour of the exhibition - an excellent program. It is great to hear an artist speaking in such normal accessible language. As he says - it doesnt matter where you are, eveything can become interesting because you are looking at it (really looking that is). The prog also helped explain his pproblem with the camera. Chinese art on a scroll was like walking through the landscape, but the european idea, derived from the use of the camera obscura, was like looking through a window, and so not in the landscape. I'm still not sure I agree - if you print a photograph big enough (like H's huge paintings) taken from the right viewpoint it can feel like you are there.
