The 2nd issue of "F-Stop" is online. This is a very interesting publication focussed on professional photographers and how they setup and light certain photos.  It gives an in depth look at how advertising photos are created (both on site w/ lighting and on the computer later) and makes you realize that the days of "simple" photography are long past.  Typically they feature 4 images w/ in-depth interviews with the photographer and drawings of how the photos were set up.  These images are part art and part science with some very complicated work behind the scenes.
