I recently read an article in Time (Feb 22, 2007) titled "If you build it they will come" which discusses Jeff Wall's "The Invisible Man" and other photographs..see article here http://www.time.com/time/magazine/article/0,9171,1592850,00.html What struck me was a line that read "Like a good director, he doesn't even always get behind the camera himself. He's directing--somebody else can click the shutter." I kept asking myself why would anyone go to so much trouble staging a photograph and then allow someone else to "click the shutter"?? I couldn't call any photograph mine if someone else clicked the shutter. Or am I being too picky?
